[00:27:30] <dMaggot> hey guys, I want to hold messages going to yahoo, but postfix seems to be ignoring the following commands
[00:27:43] <dMaggot> smtpd_recipient_restrictions =
[00:27:43] <dMaggot>                 reject_unauth_destination

[00:47:03] <xpoint> does not say much about why

[00:48:00] *** Vi5in has joined #postfix
[00:48:05] <Vi5in> Hello
[00:48:12] <xpoint> 42
[00:48:20] <Vi5in> my problems are solved! thanks!
[00:48:26] *** kreg_work has joined #postfix
[00:48:29] <xpoint> good
[00:48:33] <Vi5in> ;) anyway,
[00:48:58] <kreg_work> there a normal way to bounce an email back to notify sender of a new address?
[00:49:18] <kreg_work> like "mailbox no longer exsists, please email support at domain dot com"
[00:49:29] <kreg_work> bad example.........
[00:49:34] <Vi5in> i've installed postfix on my system.
[00:49:52] <kreg_work> i want to change a mailbox i've been using called dcc at domain dot com.   I used to receive all my support cases there
[00:50:07] <Vi5in> when i test the set up with telnet localhost 25 and doing commands to send/receive mail, it works. but I can't send anything through mutt. it says mail sent, but nothing gets sent
[00:50:13] <kreg_work> now i want incoming messages to dcc at domain dot com to be send to support at domain dot com and eventually kill dcc at domain dot com
[00:50:50] <Landon> kreg_work: just forward the mail?
[00:50:55] <kreg_work> obviously easy to get the mail delviery to work.  that's in place so i don't lose mail.   but i want the senders to be notified of the change
[00:51:00] <kreg_work> Landon: ya that's done.
[00:51:03] <Landon> and then switch all mentions of it to support@domain
[00:51:17] <Landon> and eventually turn it off when you stop getting email to it
[00:51:30] <kreg_work> wondering if there is a way to auto response "fyi, from now on please email support"
[00:52:05] <kreg_work> we have switched all mentions.  flyers, websites, etc.   but old habbits won't die
[00:54:38] <Vi5in> i have a question about local_recipient_maps in main.cf
[00:54:54] <Vi5in> I did newaliases and that creates /etc/aliases.db, right?

[01:03:24] *** x3me has joined #postfix
[01:03:26] <x3me> hi
[01:03:46] <x3me> I'm using postfix + mailscanner and I have a problem when blockin the attachments...
[01:04:07] <x3me> the problem is: postfix receives the mail to 20 recipients per example on a unique ID
[01:04:16] <x3me> and HOLD's to Mailscanner
[01:04:24] <Vi5in> i have a brand new postfix set up
[01:04:30] <Vi5in> and i'm trying to create aliases
[01:04:37] <x3me> so, mailscanner reads that ID and apply the same rule for attachments to all the 20 recipients..
[01:04:48] <x3me> solucttion I've configured: running 2 instances of postfix
[01:04:56] <Vi5in> I did "newaliases" but i am not entirely sure what that does. does it create it off the /etc/passwd?
[01:05:09] *** dMaggot has left #postfix
[01:05:10] <x3me> the first, receives the email and split them into one per one.. and them send to the other who run mailscanner ...
[01:05:14] <Vi5in> doh /etc/aliases i mean
[01:05:17] <x3me> anyone haves another soluction?
[01:06:25] <Vi5in> So I ran newaliases and now it creates /etc/aliases.db
[01:07:16] <Vi5in> does that take into account all the users i have on the box then?
[01:07:47] <Vi5in> I guess my question is are there any other steps I need to take? and also, what would be relevant changes in main.cf
[01:15:14] *** martiancode has quit IRC
[01:16:29] *** brancaleone has joined #postfix
[01:16:51] <Vi5in> ... alright
[01:16:59] <Vi5in> what is the syntax for the virtual maps?
[01:17:04] <Vi5in> in /usr/local/etc/postfix/virtual?
[01:19:09] <higuita> @domain @mapped_domain
[01:19:23] <higuita> email@domain  email@new_domain
[01:19:36] <higuita> @domain  email@new_domain
[01:20:19] <Vi5in> higuita: thanks!
[01:21:33] <higuita> of course, assuming you are using hash
[01:21:45] <higuita> you can use regexp, pcre, etc, etc
[01:22:16] <Vi5in> higuita: i only had a few, so I just wrote them out as email: username?
[01:22:40] <higuita> remove the : and its perfect
[01:23:24] <Vi5in> oh, ok!
[01:23:26] <higuita> you can check the virtual man page (man 5 virtual)
[01:23:31] <Vi5in> sweet, thanks a bunch
[01:23:42] <Vi5in> i also did newaliases after i made some changes to /etc/aliases
[01:24:33] <higuita> yes, newsaliases is for the aliases file, postmap is for all other hash files (like the virtual)
[01:25:16] <higuita> of course, regexp, pcre and other dont need postmap (hash and btree are the one that need it)
[01:27:24] <Vi5in> ah ok. i'm testing now by sending myself some mail
[01:27:38] *** magyar has joined #postfix
[01:28:38] <Vi5in> awesome :) looks like i am receiving mail!
[01:28:42] <Vi5in> now let me try sending from my box
[01:29:53] <Vi5in> hmm... some trouble
[01:30:16] <Vi5in> higuita: i am using a relay service from dyndns and it requires me to authenticate... i've kinda forgotten how to do that. would that setup exist in main.cf?
[01:31:39] *** JoeWulf has joined #postfix
[01:34:30] *** Jense has quit IRC
[01:48:16] <higuita> Vi5in: you need to setup the sasl in the smtp client
[01:48:24] <higuita> you need to check some howto
[01:48:41] <higuita> you can see the options avaiable with  postconf |grep sasl|grep smtp_
[01:49:46] <Vi5in> higuita: yeah, i tried that. but it says i need to authenticate. i followed all the isntructions here:

[11:58:10] <sysmonk> uber silent today
[11:58:28] <jgreig> hey guys I work for a hosting company, we have a postfix mail gateway for dedicated/virtual customers.  Recently a malicious south african 419 scammer spammed via our mail gateway (he was a customer at the time).  As a result our IP was blocked by hotmail/live for a day or two.  We were wondering if it was possible to have a 'pool' of IPs that can be used on postfix as sending IPs, is this straight forward? or is it easier to just alter the smtp_bind_addr
[11:58:31] <Trengo> you broke the silence
[11:58:39] *** kk_CHN has joined #postfix
[11:58:46] <sysmonk> damn it
[11:59:18] <jgreig> if you broke the silence i just nuked it.
[11:59:26] <sysmonk> jgreig: ye
[11:59:32] <sysmonk> jgreig: about the pool - not that i know of
[11:59:43] <sysmonk> we just change the bind addie
[11:59:59] <jgreig> fair enough, that's what I thought
[12:00:11] <jgreig> i did find this, though it's slightly different to what I need
[12:00:15] <jgreig> http://www.jpuddy.net/2008/05/19/how-to-email-from-specific-ips-using-linux-and-postfix/
[12:00:59] <sysmonk> yuk
[12:01:10] <sysmonk> i think it would be a LOT easier and cleaner to do it on firewall side
[12:01:20] <sysmonk> i.e. nat'ing through a pool of ip's
[12:01:43] <sysmonk> so each time a connection to host * port 25 would go through a random ip
[12:02:46] <jgreig> heh, that's a good idea
[12:03:13] <jgreig> i'll try and leech a pix or asa from somewhere in the building:)
[12:03:31] <sysmonk> or do that on the server side
[12:03:31] <sysmonk> ;)
[12:05:00] <jgreig> noted, thanks for the advice;)
[12:05:26] <shasta> keep in mind that it would require some main.cf tweaks too
[12:05:48] <shasta> as you should accept emails to username at 1 dot 2.3.4
[12:06:37] *** McJerry has joined #postfix
[12:06:50] *** fbe has joined #postfix
[12:06:53] <sysmonk> shasta: yeah, and send them to the nearest /dev/null pseudo device
[12:06:53] <sysmonk> ;)
[12:07:31] <jgreig> cheers, it's literally just an smtp gateway out of the network
[12:09:47] <fbe> simple question: is it possible to apply RCPT TO restrictions based on the MAIL FROM ?
[12:10:38] <sysmonk> um, what?
[12:12:01] *** rootsvr has joined #postfix
[12:12:06] <jgreig> is it possible to stop people coming into my house if they're already in my kitchen?
[12:12:13] <dragonheart> fbe e.g.  only jack can email jill?
[12:12:16] <sysmonk> jgreig: yes
[12:12:31] <sysmonk> jgreig: read access(5) manual page
[12:12:42] <jgreig> will do, cheers
[12:12:43] <fbe> i want some user (without smtp auth) to be restricted to only some domains for rcpt to.
[12:12:57] <sysmonk> and gun(4) man page :P
[12:13:19] <fbe> I know it's clearly not a good way to implement this (direct connection and fake mail from will bypass this). but that's not the question here
[12:13:25] <sysmonk> fbe: you might want to look into restriction classess
[12:13:29] <sysmonk> !restriction_classess
[12:13:30] <knoba> sysmonk: Error: "restriction_classess" is not a valid command.
[12:13:32] <sysmonk> !restriction_classe
[12:13:32] <knoba> sysmonk: Error: "restriction_classe" is not a valid command.
[12:13:33] <sysmonk> !restriction_class
[12:13:34] <knoba> sysmonk: "restriction_class" : postfix per-client/user/etc. access control http://www.postfix.org/RESTRICTION_CLASS_README.html
[12:13:39] * sysmonk is a flooder
[12:13:52] <dragonheart> so what package contains gun?
[12:14:40] <sysmonk> dragonheart: it's gun(4)
[12:14:42] <sysmonk> note the 4
[12:14:43] <fbe> thanks, will read this.
[12:22:08] <idle-boy> i have a server with 2 public IP, each has a domain, i want to configure postfix to sending emails using 2 domains and 2 IP,
[12:22:14] <idle-boy> for ex/ 1.2.3.4 --> example1.com, and 1.2.3.5 --> example2.com, any idea ?

[12:33:06] <fbe> you seems to be all smart people here ;-), so I will try one other stupid question (the first is resolved, thanks again): is there a way to force the relaying through a relay_host event if the destination is my_domain, and so for certain "mail from" values ?
[12:34:22] <f3ew> for mail from? use a check_sender_access and a FILTER response
[12:34:39] * f3ew also suggests using more domains and aliases
[12:37:31] *** Nockian has quit IRC
[12:37:45] * fbe should buy a new book "postfix in 5 minutes"
[12:41:51] *** hever has joined #postfix
[12:47:22] <fbe> f3ew: yeah, more domain would be better but this will be temporary during a migration in a rather tortured customer mail setup. (using msmail and pop fetch actually, yes, the precursor of ms exchange; 10 years back...)
[12:48:03] <fbe> since we have other application wo need (in database) the final adress, if I can go from the start with the final adress it's way easier.
[12:48:19] <f3ew> fbe, I meant using a subdomain to control mail routing
[12:48:24] <f3ew> It's transparent to the end user
[12:48:52] * fbe is really going to buy a book on postfix ...
[12:49:22] <fbe> I don't know about that. any howto somewhere ? (until the book arrives)
[12:49:59] <f3ew> fbe, relaying is controlled by recipient domain, so you just alias
[12:50:07] <f3ew> foo: foo at sub dot example.com
[12:50:31] <f3ew> Also see http://www.postfix.org/STANDARD_CONFIGURATION_README.html#some_local if it applies

[13:27:29] <download123> hey
[13:27:34] <download123> I need help
[13:27:47] *** dusty has joined #postfix
[13:28:05] <milligan> download123, Take a left on the first corner, first building on the right hand side.
[13:28:30] <download123> haha..
[13:28:50] <sysmonk> or hire a sysadmin!
[13:29:19] <download123> i got problems with my postfix, so i looked at the mail.log and omg its got 60000 lines only from today
[13:29:51] <milligan> if those lines are error messages, ouch. If they are logs of incoming email,jummy :)
[13:30:11] <Danskmand1> What does it say ? - always the same lines ? - do they repeat ?
[13:30:25] <dragonheart> milligan: spf verification can mark a header like http://tools.ietf.org/html/draft-kucherawy-sender-auth-header-15 however its really up to the implementation/configuration as to what it does with the email
[13:30:25] <download123> all i got from the log was that postfix tries to connect to muliple hosts but allways gets refused because of some spamhouse list
[13:31:38] <Danskmand1> Does your ISP have a smart host that you could send the mails to ? (you shouldnt send the mails directly to the receiver...)
[13:32:10] <download123> some lines look like this localhost postfix/qmgr[7691]: 1754D12200D7: from=<ubaxsjlri at albrecht-kienemund dot de>, size=26686, nrcpt=1  (queue active) what should this say to me is postfix trying to send an email to xy?
[13:32:29] *** hacim has joined #postfix
[13:33:07] <hacim> someone has just sent a phishing attempt to all of our users, I would like to block any outgoing mail to that particular user, can that be done?
[13:33:20] <download123> the problem is that the postfix is running on a hetzner server that was installed years ago
[13:34:06] <Danskmand1> Unless your domain is albrecht-kienemund.de, it looks like you are a spamming the internet.....
[13:34:07] *** stickystyle has quit IRC
[13:34:08] <e_> hm, is there a tool to print out a mail in my queue to the console?
[13:34:23] <f3ew> postcat
[13:34:29] <e_> ah, great
[13:34:31] <e_> thank you
[13:35:21] <e_> ehm, which file should i give to it?
[13:35:38] <hacim> e_: mailq queueid

[13:35:54] <hacim> postdog?
[13:35:59] <e_> hehe
[13:36:19] <e_> hacim: hm, that should be the first thing in the output line of mailq, right? like "0C02518B8757"
[13:36:24] <e_> if i do that, nothing happens
[13:36:24] <hacim> yes
[13:36:30] <download123> Danskmandl oh thats what i purposed ... how can i stop that ? or find out what has happend the server was running for years without problems
[13:36:30] <hacim> postcat -q 0C02518B8757
[13:37:10] <e_> no output
[13:37:14] *** brancaleone has joined #postfix
[13:37:25] *** cpm has quit IRC
[13:38:05] * e_ scratches head
[13:39:21] <download123> how can i stop that someone is sending spam using my postfix. I tested it over telnet and get refused but the log says that other people get it working
[13:39:25] *** cpm has joined #postfix
[13:39:32] <milligan> dragonheart, ok, sounds good. I guess it's configured to only mark on fail. How would I set it up to mark email with OK messages aswell ?
[13:39:49] <Danskmand1> Well, I am myself a starter with postfix, but know Lotus Domino very well....The server has been running very well for years - until "someone" found out that it could use your server as an "open relay" - which means that "he" can use your server to spam thousands of addresses....Could also be that they found out how to get around your anti-spam settings....
[13:40:46] <dragonheart> milligan: are you doing the verification?  I guess it depends on what software you're using.
[13:40:58] <e_> wtf.. if i strace it i can see the mail being written to stdout ^^
[13:41:08] <download123> sounds bad as first action i will stop postfix
[13:41:33] <f3ew> download123, LOGS?
[13:41:50] <Danskmand1> So,it could be that some of the people you spamed found out that it was through your server that they got this spam - and told "spamhouse" that you are an open relay.....Once you are on this list, many servers will reject your emails because you are on this list....
[13:41:59] <download123> f3ew ? what do you mean
[13:42:34] <download123> Danskmandl sounds logical
[13:42:44] <Danskmand1> What I am telling you is what I *think*, I dont know it because I have not seen your log-files....
[13:42:49] <download123> so i have to stop that other people use my server as an open relay
[13:43:02] <Danskmand1> Right....
[13:43:40] <e_> selinux
[13:43:45] <Danskmand1> Is it a big server ? - is it a big company with many users ?
[13:43:51] <download123> noe
[13:43:53] <download123> no
[13:44:33] <download123> its a small company .. i don't even know if the emails of the company run through this server
[13:44:39] <milligan> dragonheart, I'm running the dns server :) I've set up an SPF record (TXT), and it appears to be working. I'd just like some kind of verification.
[13:45:05] <download123> i hope i din't kill all mail transfers :P
[13:45:10] <Danskmand1> Ok...Then I would also find out what the smtp-smart host for your ISP is, since many servers dont want to receive emails from servers directly, better from the ISP's....
[13:45:51] <dragonheart> milligan: http://www.openspf.org/Tools email based testers - send email there and look at the response
[13:46:29] <download123> Danskmand1 as far as i see the server is configured to use an ISP from Hetzner but the ISP also rejects requests ;)
[13:47:01] <Danskmand1> But first, show your Log-files (parts of it) - all I told you up to now is only theory, since we havent seen your logfiles !
[13:47:19] <Danskmand1> But I need to leave now ..... be back later ....
[13:47:20] <download123> okay.. latest entries ?
[13:47:25] <download123> well
[13:47:33] <download123> thank you for your help
[13:47:39] <Danskmand1> Right ....latest entries....
[13:48:11] <Danskmand1> And have a look at your main.cf of postfix...
[13:48:28] <Danskmand1> Thats the main config file....
[13:48:40] <Danskmand1> You are welcome :-) - Have fun !
[13:48:51] <Danskmand1> I will ask my question later :-)

[13:53:07] <download123> the last few entries
[13:58:03] <download123> is my interpretation correct that someone tries to send emails over my server over smtp to AnneBauer at currentmail dot com and KarlEnderbvurp at myfirstmail dot com etc?

[14:01:00] <download123> no one left?
[14:01:09] <sysmonk> how much money you have?
[14:02:18] <download123> at the moment none
[14:04:17] <cpm> Not sure I understand. the server @ 213.239.211.232 is blacklisted.
[14:05:51] <download123> jep
[14:06:07] <download123> well .. this is my server
[14:06:13] <shasta> hacim, check_recipient_access of course
[14:07:06] <cpm> it's listed in the cbl, http://cbl.abuseat.org
[14:07:08] <cpm> my question is why?
[14:07:16] <cpm> you are acting as an open relay?
[14:08:20] <download123> sems so .. i don't realy know
[14:08:53] *** noneo has joined #postfix
[14:09:42] <download123> it seems as if the server is spamming
[14:09:55] <download123> prob is i don't know how its done
[14:10:06] <shasta> you shouldn't run a mailserver then
[14:10:21] <shasta> sad but true
[14:10:29] * shasta sings to the metallica's tune
[14:10:33] <hacim> shasta: ok, great....thanks. one last related question: check_sender_access is the email address that the message claims to be from, and check_client_access is the actual ip or host of the machine that the message is coming from?
[14:10:52] <download123> well .. what i wanted to say is that i tryed to use it as an open relay .. and get refused
[14:11:09] <shasta> hacim, man 5 postconf has the answers you need
[14:11:27] <hacim> in otherwords, this scammer is impersonating "info at mail dot com", and that is not a valid address, so I would add a line to check_sender_access to REJECT that, and add a line to REJECT the last hop in the header in check_client_access
[14:12:05] <hacim> right, man 5 postconf... just was reading it, and wanted to verify what I found
[14:15:15] <hparker> download123: Is the same system the router for the LAN with 'doze systems behind it?
[14:15:46] <download123> no its a webserver (root server)
[14:15:51] <download123> hparker
[14:15:53] <cpm> ah ha
[14:15:58] <hparker> Bad scripts?
[14:16:09] * cpm wouldn't bet against it.
[14:16:13] <hparker> Any email forms?
[14:16:31] <download123> no script
[14:16:40] <cpm> is it running php at all?
[14:16:49] <download123> php is running
[14:16:56] <hparker> does it have users other then you?
[14:17:03] <cpm> check the box to see if it has been rooted
[14:17:12] <hparker> and that
[14:17:46] <download123> hparker its the rootserver of the company but normaly no one else is on the system than me
[14:17:54] <download123> cpm witch box?
[14:18:21] <download123> sry i'm not that close with linux
[14:19:24] <hparker> If it's for a company they ought to pay for a competent admin to run it :P
[14:20:13] <hparker> How long have you been listed?
[14:20:34] <download123> :-P my opinion .. but the company is to small and the normal admin is on vacations
[14:21:04] <hparker> Admins carry laptops on vacation... just in case...
[14:21:37] <hparker> You're going to need to go through the logs and see if you can figure out where the mail is coming from that's causing the problems
[14:23:04] <cpm> hparker, he's only been listed for a few hours, so the hack probably happened recently.
[14:23:20] <hparker> ahh... Then should still be in the logs
[14:23:31] <cpm> <download123> sry i'm not that close with linux
[14:23:36] <cpm> then you need to find someone who is.
[14:23:52] <hparker> yup
[14:23:52] <cpm> contact the on-vacation admin

[14:24:35] <hparker> That's just a normal ssh attack

[14:24:55] <cpm> just for fun, pastebin the output of the command:
[14:24:58] <cpm> qshape all
[14:25:17] <hparker> Seriously, admin's can't travel without a way to connect back.. especially if they're the only admin
[14:25:33] <cpm> qshape deferred rather
[14:25:45] <cpm> quite so.
[14:26:00] <download123> hparker .. if the boss knows that something like that can happen .. etc
[14:26:19] <hparker> now he knows

[14:33:29] <hparker> xpoint: hehe
[14:35:20] <xpoint> download123, if you use postfix and not exim its not that hard to do the things right, but trace the logs why you are blacklisted, and recerse track it to where the reason comes from, if its domain based blacklist its still your ip
[14:36:21] <xpoint> senders should really use sasl on php scripts or get relay denied

[14:46:59] <canburak> hi,  i'm piping contents of all mails to a filter (spamc).  my active queue has ~1000 mails and postfix seems to spawn ~50 spamc processes.  spamd's max-child limit is at 128. i want to find out how to check the cause of this.
[14:47:01] <xpoint> its smtpd
[14:47:58] <download123> xpoint that isnt the smtp service?
[14:48:00] <xpoint> download123, postfix is server not client
[14:48:09] <cpm> "240 and so on"
[14:48:16] <cpm> yeah, I'd say that box was compromised
[14:48:38] <cpm> you *NEED* to contact the admin of that system. Now is better than later.
[14:49:47] <download123> okay well ill contact the boss but one last question ...
[14:50:15] <xpoint> will we deliver pitza ? :-)
[14:50:29] <download123> is that log pice above a prove that the spam mails where injected to the server using smtp and a hacked login?

[14:56:07] <download123> well .. one thing i don't understand ... how does this mail get in there
[14:57:29] <xpoint> sender or recipient is local or sender used smtp auth, but the logs above shows no smtp auth user
[14:58:21] <download123> oh okay
[14:58:22] <xpoint> or using pop-before-smtp, heaven forbids that, but it could be this to
[14:58:30] <cpm> xpoint, and you are saying the box isn't hacked because of what exactly?
[14:58:34] <download123> so smtp auth would insert some data in the log?

[15:07:12] <hacim> is the 'envelope from' the address that can be faked in a SMTP session when doing MAIL FROM: ?
[15:08:35] <shasta> all addresses can be faked

[15:09:42] *** shoonya has joined #postfix
[15:09:44] <hacim> i guess I am looking for the terms... the From: header is called the "evelope from"?
[15:10:36] <shasta> EHLO foobar.e.h.lo
[15:10:37] <xpoint> thats why sasl is usefull for local users to

[15:12:38] <xpoint> hacim, you
[15:12:50] <hacim> shasta: ok, and most mail clients will only show the envelope from unless you look at the full headers?

[15:13:09] <hacim> the other way around

[15:14:33] <xpoint> unless the sender uses smtp auth
[15:14:46] <hacim> right, so how does the envelope from show up in the headers? as a Received: line?
[15:14:55] <xpoint> but even there he can still use forged from: !

[15:19:13] <hparker> never a problem for me
[15:19:19] <xpoint> hparker, even on gentoo
[15:19:24] <hparker> nope
[15:19:29] <hparker> got a few running atm
[15:19:38] <xpoint> hparker, you need to search more then
[15:19:50] <hparker> I don't go looking for trouble ;)
[15:20:00] * cpm doesn't have these phantastical mailman 'bugs'.
[15:20:07] <xpoint> but thay do exists
[15:20:23] <shoonya> ok, i guess i was not clear with my question. i am not using/looking for a mailing list manager
[15:20:50] <cpm> shoonya, that's almost exactly what a mailing list manager does.
[15:20:53] <xpoint> shoonya, or even mlmmj ?
[15:20:58] <cpm> that's the correct tool for the job you described.
[15:21:12] <shoonya> what i mean is lets say if there is a email id as myname at mydomain dot com, can i control who can send mail to this id using postfix ?
[15:22:07] <xpoint> yes no problem if you run it on a lan with no internet access
[15:22:09] <shoonya> i mentioned group@... because this email id could be an alias for all users
[15:22:10] <cpm> can probably do with it some clever maps and transport.
[15:22:28] <cpm> yeah, I use mailman for that purpose, Have for many years. Works well.
[15:22:30] *** kRocKodile has quit IRC
[15:23:12] *** canburak has left #postfix
[15:23:17] <shoonya> any solution possible using postfix alone ?
[15:24:45] <xpoint> i will not suggest messy configs, but if you want it, postfix can make it with classes, but it will be very messy
[15:25:33] <xpoint> it will be more clear to every user on this why mailman is the way to go in the end
[15:25:52] <hparker> and then have to learn mailman :P
[15:25:59] <shasta> or a policy daemon :>
[15:26:13] <xpoint> or use mlmmj if one need a lightweight solution
[15:26:47] <xpoint> hparker, python is scarry :-)
[15:26:57] <shoonya> is there any policy daemon for this requirement
[15:27:13] <shasta> write one, shouldn't be that hard
[15:27:21] <xpoint> !google policyd v2
[15:27:22] <knoba> xpoint: Error: "google" is not a valid command.
[15:27:29] <hparker> xpoint: heh... I have to go back to the docs every new list I setup, fortunately that's not many
[15:27:30] <xpoint> dmm
[15:27:31] <shoonya> that's really hard for me :)
[15:28:14] <xpoint> hparker, web create new list works for me
[15:28:17] *** AcTiVaTe has joined #postfix
[15:28:33] <hparker> xpoint: heh.. I hate web interfaces ;)
[15:28:37] <xpoint> hparker, but its a mess config i have
[15:28:39] <cpm> mlmmj might be a better answer
[15:28:59] <cpm> mailman is a very handy application, worth learning
[15:29:18] <PcPixel> can you use multiple maps with relay_recipient_maps?
[15:29:40] <cpm> sure, first match wins
[15:29:40] <xpoint> hparker, and you still use mailman, hmm :-)
[15:29:46] <dragonheart> I didn't really follow you xpoint however have you looked at reject_authenticated_sender_login_mismatch ? I've also used mailman for many purposes.
[15:29:59] <hparker> xpoint: I host < 10 lists, no biggie
[15:30:00] * cpm has used mailman for over a decade. Is pretty fond of it.
[15:30:20] <cpm> does hit nasty bugs from time to time, true enough.
[15:30:49] <xpoint> dragonheart, yes it can be done, but its messy :=)
[15:32:29] <xpoint> hparker, mailman have its quirks, here i got it working with postfix virtual domains, but just use non virtual setup in postfix, so postfix just reads the alias pipe list and nothing more, it crap config but it works :)
[15:33:10] <hparker> I use @lists. as a local domain for those that want a list
[15:33:32] <xpoint> hparker, have to figure out how to make real web create with virtual maillist via webud create
[15:33:57] <hparker> Now you see why I do it all manually ;)
[15:33:57] <cpm> I managed to get mailman working with virtual domains in mysql a while back, didn't bother writing up how I did it though. was really proud of it at the time too
[15:34:28] * hparker still has dents in his forehead from trying to get it going virtual
[15:34:39] * PcPixel giggles
[15:34:41] <xpoint> cpm, make a patch to mailman  ?
[15:34:46] <cpm> xpoint, nope.
[15:34:56] <xpoint> so its lie :-)
[15:35:22] <cpm> No, worked okay. Some bletcherous regexp matching in mailman aliases thoug.

[15:37:37] <xpoint> hparker, thats all i did here
[15:38:12] <xpoint> hparker, this only wiorks with one virtual domain through
[15:38:58] <g0rd0n> what config parameter is it that rejects mail from servers that do not have a reverse dns on ther ip?
[15:39:00] <hparker> Yeah, I added @lists to mydestination and use them all as local domains
[15:39:41] <xpoint> hparker, since pipe only works with local :-)
[15:40:11] <hparker> heh
[15:42:33] <xpoint> g0rd0n, try remove one restrictions until you find it, na i dont remember exactly what one do this

[15:47:06] <hacim> shasta: yeah, I have permit_sasl_authenticated before :p
[15:47:48] <xpoint> he sender is blacklisted, but its sent from local
[15:48:05] <xpoint> thats why it creates a bounce
[15:48:37] <download122> xpoint that was grep CD1181220634 /var/log/messages
[15:48:39] <xpoint> then reject_unlisted_sender

[15:49:52] <download122> xpoint to me?
[15:50:01] <xpoint> and reject if bounce is not possible :)
[15:50:24] <xpoint> trace why it bounces
[15:50:46] <xpoint> and reject before you need to bounce, solves the problem
[15:51:24] <xpoint> queue id is the trace pointer

[15:52:33] <fbe> is it possible to overide relayhost using -orelayhost=xxxx of the sendmail compatibility interface ?
[15:53:11] <xpoint> fbe, in master.cf yes
[15:53:28] <download122> other question .. easyer to completly reinstall postfix or try to fix it
[15:54:03] <xpoint> download122, its more easy to make more coffie :-)
[15:54:25] <cpm> easier to get the admin who built it to deal with it.
[15:54:28] <xpoint> download122, but you learn more by fix the mess
[15:55:04] <cpm> personally, if someone here decided to hamfist one of my servers, rather than call me, I'd have them killed, at some time in the future, when they weren't expecting it.
[15:55:12] <fbe> so, is there a way to specify alternative main.cf for a given "sendmail" run ?
[15:55:25] <cpm> hire xpoint to do it.
[15:55:53] <xpoint> fbe, sendmail is pickup in master.cf
[15:56:17] <xpoint> fbe, configure pickup as you like
[15:56:29] <download122> cpm the admin isnt in the company and the guy i thought is admin has lass knowlledge about linux than i

[15:57:54] <download122> its a root server where apache and postfix is installed

[16:19:00] <ribasushi> ever heard of preventive checks?
[16:19:31] <PcPixel> yeah something is up when i implement it. my map files cause all mail to get kinda "lost"
[16:19:33] <cpm> I've heard of reading the rfcs yeah.
[16:19:46] <cpm> PcPixel, lost?
[16:19:52] <cpm> can you give an example?
[16:20:04] <PcPixel> cpm: it never makes it into the server
[16:20:13] <PcPixel> if i implement relay_recipient_maps over the check i was doing, mail stops coming in

[16:21:59] <PcPixel> there's a start

[16:22:55] <cpm> one map 'type'
[16:22:55] <Trengo> ribasushi no idea, sorry
[16:22:57] <PcPixel> cpm: to which
[16:23:07] <cpm> you probably should combine them to one db.
[16:23:17] <PcPixel> cpm: thats what i was asking earlier :)
[16:23:19] <cpm> rather than hashing all those files, combine them to one.
[16:23:25] <PcPixel> i was just about to dfo that & make it a single line
[16:23:32] <PcPixel> and see if that makes a difference
[16:24:10] <cpm> Thought you were maybe doing a regex, a hash, a db lookup, or similar. That should work however, but that's a lot of lookups. Better to combine them, and hash one db file, will take a whole lot less effort. But in theory, it's not exactly wrong.
[16:24:37] <PcPixel> cpm: ok cause if i do that & enable it versus my other checks, its like mail just stops flowwing in
[16:24:58] <PcPixel> the contents of the file are currently valid at qddress dot com OK and i saw that it just needs any value on the right side so i should still be ok
[16:25:23] <cpm> Umm, not sure that will work.
[16:25:42] <PcPixel> the documentation said it just has to be an address on the left, and any value on the right
[16:26:24] <cpm> not exactly, close. "valid addresses in the domains that match $relay_domains"

[16:26:51] <PcPixel> all the ones i have listed are listed in relay_domains

[16:27:00] *** Internat has joined #postfix
[16:27:03] <PcPixel> cpm: correct :)
[16:27:17] <cpm> okay. then combine all that crap into one file, and hash that. be sure to postmap it.
[16:27:36] <cpm> then check it with postmap -q 'value' hash:/path/to/file
[16:27:45] <PcPixel> that was my next step :) and its fine to leave the OK's right
[16:27:53] <cpm> yeah, think so.
[16:27:58] <PcPixel> poifect
[16:27:59] <cpm> why are you doing this?

[16:51:57] <dusty> Hey guys, I need an experienced opinion. I have just aquired a new VPS (Virtual Private System) like guest os using openvz.  The specs are: 256mb ram, 30gb hd, 200mb connection.  I want to setup a new mailserver on there, it is also running apache for two domains that don't have too much traffic.  My question is, if I don't use amavis and stick to plain ole postfix/dovecot/mysql will the server handle that ok, or will there
[16:51:58] <dusty> be memory issues ? The reason i'm asking is I don't want to put the hard work into setting it up to find it borks on memory as I cannot get it upgraded.  I currently run a postfix/dovecot/amavis/mysql mailserver which munches a lot of ram, around 512 - 1gb.  Im pretty sure thats mainly amavis consuming it and to be honest im going to drop amavis for other methods in my new setup, whats everyone's thoughts ?
[16:52:14] <dusty> (Did that cut my question, if so where) ?
[16:52:54] <ribasushi> f3ew: the complexity of the fine control you have over the system must be warranted by something
[16:53:03] *** bacaci has left #postfix
[16:53:20] <ribasushi> f3ew: security for the sake of security is... dunno
[16:53:50] <PcPixel> cpm: ok, one file worked
[16:54:18] <f3ew> ribasushi, depends on the actual requirements
[16:54:25] <f3ew> It's needed for a webhost
[16:55:28] <PcPixel> that should help things out. now ive got that recipient check out of the smtpd_Recipients_restriction
[16:56:23] <PcPixel> leave my other classes/etc in there, but the check commented out & see how things go
[16:57:53] <PcPixel> is SELinux even worth it
[16:58:16] <dusty> do you offer accounts on the mailserver to people you don't trust ?
[16:58:28] <dusty> or do you have users other than yourself on that system ?
[16:58:31] *** Draecos has quit IRC
[16:58:34] <PcPixel> mailserver is a relay and no. ssh only by admins
[16:58:42] <dusty> then i wouldn't bother.
[16:59:07] <dusty> If you had local users on there then I would.
[16:59:24] <PcPixel> i love it
[16:59:26] <dusty> or if you had users interacting with the system other than collecting/sending mail.
[16:59:28] <PcPixel> im pissing my boss of with reboots
[16:59:32] <dusty> hah
[16:59:37] <PcPixel> why the heck hes camping out on my email server i dont know
[16:59:42] <dusty> by the way, anyone have any opinions on my question?
[16:59:47] <PcPixel> ive had to reboot it 4 times to get selinux to pick up the changes
[17:00:18] <dusty> Would 256mb of ram on a vps be not enough for postfix/dovecot/mysql ? (bearing in mind it has apache on there also, hosting two vhosts).
[17:00:30] <fdask> try it and see
[17:00:32] <PcPixel> depends on your vilume
[17:00:38] <PcPixel> volume
[17:00:39] <fdask> i'd say yeah, depending on your apache/postfix settings
[17:00:42] <fdask> and volume, sure
[17:00:54] *** morpheus08 has quit IRC
[17:00:57] <dusty> yes as in it would need more memory
[17:01:00] <roe_> are you SAing somewhere else or forgoing spam scanning completely?
[17:01:01] <dusty> or yes as in it would suffice ?
[17:01:12] <dusty> roe_, me ?
[17:01:15] <roe_> yes
[17:01:19] *** xpoint has quit IRC
[17:01:38] <dusty> I am not using SA on my new mailserver im going to try other methods such as black lists, etc.
[17:01:48] <dusty> im going to look into what postfix has to offer
[17:01:57] <dusty> as SA is written in perl and uses far too much memory
[17:02:00] <dusty> well, amavis.
[17:02:02] <PcPixel> ive got a nicely powered system right now & its not breaking a sweat
[17:02:13] <dusty> beautful
[17:02:16] <dusty> beautiful
[17:02:19] <roe_> dusty, good luck with that
[17:02:21] <PcPixel> but not what you stated
[17:02:35] <dusty> roe_, what do you mean ?
[17:02:48] <dusty> Hey, i'm open to opinions/ideas so blast them at me :)
[17:02:52] *** mark-use has joined #postfix
[17:03:02] <dusty> I just found amavis very confusing, very hard to troubleshoot problems.
[17:03:02] <PcPixel> more RAM for starters
[17:04:30] <roe_> those are not reasons to try to extend postfix into a realm it was not written for.  You can definitely limit how much email hits your spam scanning software but I would not try to make postfix into a spam detector
[17:04:42] *** g0rd0n has quit IRC
[17:04:46] <PcPixel> i agree w roe
[17:05:06] *** g0rd0n has joined #postfix
[17:05:47] *** conjurous has quit IRC
[17:06:20] <download122> how can i delete all emails that were in wait list of postfix
[17:06:22] <download122> ??
[17:06:27] <PcPixel> cpm: dang it they are delayed again
[17:06:37] <PcPixel> or not showing up
[17:08:06] <PcPixel> ok, i need a test server. i cant keep doing this.
[17:08:27] <roe_> what? take down your primary email server in the middle of a work day?
[17:08:54] <PcPixel> especially wheni cant tell my $@#! boss is working on it at the same time
[17:08:57] <dusty> roe_, hrm ok, maybe I need to look more into the spam aspect of things.
[17:09:08] <dusty> roe_, what would you suggest for spam control then ?
[17:09:13] <roe_> amavis :)
[17:09:18] <dusty> heh
[17:09:33] <roe_> what distro do you use?
[17:09:35] <PcPixel> im doing a bunch of spamchecks w/o amavisd
[17:09:42] <PcPixel> and im at about 10% good 90% rejected
[17:09:57] <dusty> roe_, currently, ubuntu server. However i'm open to opinions I can stick any os on there.
[17:11:06] <roe_> well postfix supports blacklist checking, which you definitely should do, the nice thing about amavis is that it is one scanner that will do spam and virus checking, doing SA and virus without is definitely possible and relatively easy, but give you fewer options
[17:11:31] <dusty> roe_, another problem with amavis is, postfixadmin breaks the tables, there is no id column where amavis does a lookup against it and breaks because of it.  I need postfixadmin so users dont hastle me for password changes etc.
[17:12:06] <dusty> roe_, I would stick with amavis if I could fix the issue where it breaks tables.
[17:12:34] <roe_> you want to give them per user control of the spam settings?
[17:13:11] <dusty> that would be awesome i have not delved into that yet though
[17:13:28] <dusty> I want users to be able to control their own spam, and manage their own account (e.g. password changes)
[17:13:46] <dusty> hence the reason for postfixadmin
[17:13:58] <roe_> I'm not sure why amavis cares about your users, especially if postfixadmin doesn't support spam settings
[17:14:12] <dusty> let me show you
[17:14:13] <dusty> hang on a  sec
[17:14:33] <dusty> http://paste.stoned-hacker.co.uk/35
[17:14:38] <dusty> check that out, thats where it breaks
[17:14:51] <ribasushi> dusty: do you do greylisting? it is still amazingly effective
[17:15:07] <dusty> I dont do anything like that yet, amavis has handled everything so far.
[17:15:12] <dusty> e.g. spam/av stuff
[17:15:18] <dusty> postfix just did plain ole mta stuff
[17:15:28] <ribasushi> I doubt amavis can do greylisting
[17:15:38] <ribasushi> dusty: look into postgrey
[17:15:48] <dusty> yeah that was what i was going to substitute amavis for
[17:15:49] <PcPixel> yeah postgrey is good
[17:15:55] <dusty> postgrey and a few other things
[17:15:58] <dusty> rbl checks etc
[17:16:17] <roe_> dusty, not sure how your amavis is configured, but it does not need to do that sql query to operate properly
[17:18:11] <dusty> roe_, i've been here before I could not disable the sql stuff.
[17:18:23] <dusty> i commented out every sql line in amavis.conf and it still performed sql lookups
[17:18:44] <roe_> if you are using ubuntu don't you have a /etc/amavis/conf.d?
[17:19:10] <ribasushi> dusty: this is what I do, works amazingly well (6 domains, about 15 accounts in each, about 20 spam messages total a week)
[17:19:11] <ribasushi> http://pastebin.com/m314dd6d3
[17:20:30] <ribasushi> it's mainly google spam that gets through
[17:22:43] <dusty> roe_, yes, but not many are familiar with that.
[17:22:48] <dusty> roe_, ill show you the sql stuff now
[17:23:07] <dusty> but the thing is, if i comment it out, or just remove the sql syntax then restart amavis it still does sql stuff
[17:23:25] <roe_> then you missed something :)
[17:23:42] <dusty> nope
[17:23:49] <dusty> unless its not related to the term 'sql'
[17:23:58] <dusty> as I grepped everything to do with amavis for sql
[17:23:59] <roe_> which is very likely
[17:24:02] <dusty> ok
[17:24:04] <dusty> doh
[17:24:27] <PcPixel> time for lunch
[17:24:29] *** PcPixel has quit IRC
[17:24:38] <dusty> Do you have the time to help me out with this? you seem to know a bit about amavis and it may help me out no end (as I won't have to research a new setup) ?
[17:25:01] <ribasushi> dusty: if you are ever in a situation where you think a piece of software is doing stuff wrong the odds are: it is wrong - 1%, the hardware is faulty - 0.1%, you are wrong - the rest :)
[17:25:06] <roe_> I was about to follow PcPixel's lead
[17:26:13] <roe_> ribasushi, I guess you have never tried to get debian running on a sparc before :)

[18:10:37] <g0rd0n> sorry if i repeat my question, but there has been screen flooding :P
[18:10:39] <g0rd0n> i'm using policy-spf, but i noticed that for every recipient in CC, postfix will insert one Received-SPF header. so, in my case i got an email with 1 To address anad 18 in Cc, and i got a total of 19 headers saying the same thing... is this a bug or a misconfigration?

[18:18:56] <jcrites> hi
[18:19:12] <jcrites> I was wondering if someone could tell me where I might research to find the answer to the following question ...
[18:19:15] <g0rd0n> rob0: hmmm im calling it at the end of smtpd_recipient_restrictions
[18:19:41] <g0rd0n> check_policy_service unix:private/spfpolicy, check_policy_service inet:127.0.0.1:2525, permit
[18:19:47] <jcrites> originally we configured our mail hosts like mail-001.example.com, mail-002.example.com.  back then each number corresponded to one actual machine.
[18:20:04] *** saurabhb has quit IRC
[18:20:26] <jcrites> at some point, we moved IPs and DNS around, so the numbers became meaningless and unnecessary.  we tried naming the records like mail-c-d.example.com where c,d were the last octets of the IP address a.b.c.d
[18:20:34] <jcrites> but that's annoying and seems superfluous
[18:20:46] <jcrites> so my question is:  is there any disadvantage to putting all my mail servers under one FQDN?
[18:21:06] <jcrites> for example, I could have mail.example.com as the A record to each IP address I have, with PTRs back
[18:21:07] *** Tykling has joined #postfix
[18:21:36] <jcrites> I am wondering whether this is (1) correct under SMTP standards (2) likely to get our domain blocked or something else.  what would be a good resource to research this kind of thing?
[18:21:40] <g0rd0n> jcrites: this is normal practice, as far as i know
[18:21:56] <jcrites> oh really?  maybe I'm looking at bad examples then :)
[18:22:00] <g0rd0n> you mean you want to use one fdqn as a round robin, right?
[18:22:16] <jcrites> well, this is actually for our corporate outgoing mail servers, not the incoming
[18:22:27] <jcrites> I got a load balancer for the incoming mail already
[18:22:28] <rob0> Oh I don't know about normal practice, I think most big mailers use different names for each machine.
[18:22:38] <g0rd0n> hmmm...
[18:22:42] <jcrites> like google for example
[18:22:52] <jcrites> google.com MX smtp1,2,3,4.google.com
[18:22:59] <rob0> MX is not outbound
[18:23:08] <jcrites> oh, stupid me
[18:23:09] <rob0> you're comparing apples and oranges
[18:23:29] <g0rd0n> as long as your smtp reply with the HELO that equals the rdns reply
[18:23:30] <g0rd0n> it should be fine
[18:23:39] <jcrites> yeah but I still see a lot of that kind of thing on the outgoing side too
[18:23:55] <rob0> yes, and avoid hostname patterns which look dynamic
[18:24:42] <jcrites> ti-out-0910.google.com ([209.85.142.188]) looks to be one of the outbound gmail servers
[18:24:45] <rob0> mailX.example.com where X is a single digit is good
[18:25:13] <jcrites> right -- so what I am asking is whether mail servers need different FQDNs at all, whether there would be any disadvantage from calling them all mail.example.com
[18:25:15] <rob0> but then, no one can anticipate what some fool will come up with as a FUSSP
[18:25:54] <rob0> The only disadvantage I can think of is that it might be a bit harder to diagnose in case of problems.
[18:26:10] <jcrites> think spam blocking solutions might.... do something?
[18:26:19] <jcrites> for example, if any ISP rate-limits on FQDN I'll be screwed.  or similar

[18:27:54] *** error404notfound has joined #postfix
[18:27:54] <fbe> is there a way to override transport_maps in master.cf (-o option ?)
[18:28:04] <rob0> There are far more idiots trying to fight spam than there are spammers. But see above ... just use good sense and that's the best you can hope for.
[18:28:04] <jcrites> thanks for the help rob, gordon
[18:33:04] <cpm> rob0, yeah, true. But the spammers make more money
[18:34:30] <rob0> unfortunately so
[18:35:54] <rob0> Yet, I'm sure that all the money spent on spam abatement is FAR higher than the total revenues of the spam industry.
[18:37:08] <cpm> rob0, no doubt. But it's a revenue-effort/results ratio. The spammers will ALWAYS win, as long as folks buy their goods. It's pretty simple.
[18:37:47] <cpm> Dont' for one second think that Pfizer hasn't made horrifically large fortune off of 'that bad viagra spam, shame shame'

[19:12:55] <dan> I'm struggling with understanding how to make postfix use TLS along with relayhost.  I don't have any local delivery, all mail goes to my ISP's server and it was working but they just decided to use TLS on their server.

[19:17:45] <lunaphyte_> don't forget smtp_use_tls
[19:17:47] <f3ew> postconf | grep smtp_tls <=== all relevant variables
[19:17:52] <f3ew> that too
[19:17:54] <dan> I have the smtp_use_tls

[19:47:51] <davidj> I'm looking for help with Postfix.  I've got a postfix server at a remote office configured with relayhost=mail.wan.  mail.wan is in our dns and resolves correctly.  When someone at the remote office emails someone at another site, the message gets deferred with "Unknown user".  How do I tell Postfix to forward all mail to the relayhost, not just non-local mail?

[19:54:03] <davidj> Should relay_hosts = mail.wan or [mail.wan] ?
[19:54:35] <Freddie`> is there a way to serve multiple domains without using mysql/postgresql ?
[19:54:36] <davidj> iirc, [mail.wan] prevents postfix from looking for an mx record for mail.wan.  Is that correct?
[19:55:14] <davidj> Freddie`: I've seen several examples today that use ldap instead of sql databases for multiple domains.

[20:39:30] <e-head> Hey, anyone around?
[20:39:43] <e-head> hey Gershwin
[20:40:02] <e-head> I'm trying to send mail from a Site5 hosted account to unite.org.
[20:40:34] <e-head> I get back a "Mail delivery failed" message saying "The mail server could not deliver mail to lynn.***** at unite dot org.  The account or domain may not exist, they may be blacklisted, or missing the proper dns entries."
[20:40:59] <e-head> In all liklihood, is this the unite.org server slamming the mail for some reason?
[20:41:10] <cpm> what say the logs?
[20:41:23] <e-head> ahh. Unfortunately, I don't have access to the logs on either server.
[20:41:43] <e-head> So, this makes it harder to pin point what's going on.
[20:41:50] <cpm> Yup.
[20:42:00] <e-head> I do know this much... the account lynn.*** at unite dot org DOES exist.
[20:42:09] <e-head> I can send mail to her from my gmail and verizon accounts.
[20:42:10] <lunaphyte_> prove it.
[20:42:16] <e-head> ha
[20:42:19] <lunaphyte_> heh
[20:43:08] <e-head> Oddly enough, I can't get mail from her either. So, the two servers are having definite problems talking.
[20:43:25] <lunaphyte_> presumably, the server having the conversation with unite.org's mx would have additional insight.
[20:43:39] <e-head> exactly.
[20:43:44] <davidj> Can I set a size limit on incoming messages?
[20:43:52] <e-head> If I could get my hands on the relevant log entries it would definitely help.
[20:44:24] <e-head> So... I guess I'm asking what is the most likely scenario(s)?
[20:44:27] <lunaphyte_> why can't you?
[20:44:43] <e-head> I emailed them to ask. Havn't heard back from them yet.
[20:44:50] <lunaphyte_> who?
[20:45:06] <e-head> The sending SMTP server (Site5 hosted).
[20:45:12] <e-head> I don't administer either server.
[20:45:16] <lunaphyte_> oh, i see.
[20:45:18] * rob0 sings ... "'Cuz I'm down in Folsom Chroot ..."
[20:45:21] <e-head> I used to, but then we moved it to site5.
[20:45:33] <rob0> The Geek in black
[20:45:56] <lunaphyte_> you are trying to be the admin, but are not the admin.
[20:46:04] * cpm rejoins 'An I see that chroot a'running, on down to rob0'
[20:46:06] <e-head> exactly.
[20:46:08] <e-head> ;)
[20:46:30] <e-head> My boss doesn't understand this. He thinks somehow I should know all the answers. I tried to tell him it's sort of like 2 black boxes.
[20:46:43] <rob0> Well e-head, the error you pasted here is not from Postfix, so perhaps that will help narrow it down further.
[20:47:06] <e-head> It's relatively rare for an outgoing SMTP server to run a lot of checks once it's authenticated the sender, correct? I mean... it will verify the sender, sure, but then beyond that it just tries to go ahead and send the mail.
[20:47:07] <lunaphyte_> yeah, that looks like an error from pistfox.
[20:47:10] * davidj adds "I killed a pid on Jackson, just to see how it would die"
[20:47:16] *** devdas has joined #postfix
[20:47:31] <cpm> or an error from lunafox
[20:47:40] <e-head> So... I'm thinking it's the receiving server (unite.org), that is slamming the message.
[20:47:40] <rob0> John E-cash
[20:47:44] <lunaphyte_> davidj: postconf | grep -i size
[20:47:52] <davidj> lunaphyte_: Thanks!
[20:47:59] * cpm falls over
[20:48:07] <davidj> rob0: owww ;-/
[20:48:22] <rob0> e-head, do you think somehow WE should know all the answers without any information?
[20:48:23] <lunaphyte_> i think it's site5 being sucky, and unite.org being picky.
[20:48:37] <lunaphyte_> then we guess!
[20:48:47] <e-head> Now... would you guys happen to know this much.  The error given in the "Mail Delivery Failed" message... is that in all liklihood the error the unite.org server (receiving) gave the sending SMTP server, and the sending SMTP server just passed it along to the sender.
[20:48:52] *** harlan__ is now known as harlan
[20:49:15] <rob0> Or the MUA, or the relayhost ...
[20:49:47] <e-head> It's not the MUA I don't think.
[20:50:07] <e-head> The message came from the sending email server.
[20:50:17] <e-head> Where it cooked up the message though I have no idea.
[20:51:08] <e-head> My guess... it tried to send the message, got a denial error code from the receiving server (something like "550-The mail server could not deliver mail to"), then it just passed then back to me (the sender).

[20:53:07] <e-head> I don't think you are supposed to use IP addresses in MX records.
[20:53:08] <lunaphyte_> yay for michigan!
[20:53:14] <lunaphyte_> i swear it's not mine.
[20:53:14] <rob0> NO, that is NOT a valid MX entry.
[20:53:34] <e-head> Because it's not a FQDN, right?
[20:53:36] <rob0> So any site that delivers to that domain is broken.

[20:57:22] <davidj> lunaphyte_: IP addresses aren't supposed to have trailing dots.
[20:57:56] <lunaphyte_> i wish i left a trail of dots, like the family circus cartoons.

[22:27:55] <PcPixel> i havent had a problem with it yet. only real thing im doing is the reject_multirecipient_bounce
[22:29:15] <PcPixel> or however the parameter is defined :P
[22:32:03] <Gershwin> interesting... considering that i've never looked at qmail, it's good to hear about this little stuff w/o having to investigate

[22:32:21] <Gershwin> little/just right/big stuff
[22:36:33] <sysmonk> Gershwin: we overdozed ofcorse, but there's some truth in what we say
[22:36:46] <sysmonk> you need to apply hundreds of patches for it to work well
[22:37:03] <sysmonk> but what rob0 said is truth
[22:37:18] <sysmonk> magyar_: we're not fighting it, we're sending it!
[22:39:50] <magyar_> sysmonk, hmmm? didn't get it..
[22:41:47] *** tshine has quit IRC
[22:42:37] <sysmonk> magyar_: nah, just joking, but i did find out about a few backscatter-sources on my network, already patched
[22:43:01] <sysmonk> magyar_: i don't know of any good way of fighting it thought
[22:43:03] <magyar_> PcPixel, what is "reject_multirecipient_bounce" ?
[22:43:08] *** F6F has joined #postfix
[22:43:24] <sysmonk> !reject_multi_recipient_bounce
[22:43:24] <knoba> sysmonk: Error: "reject_multi_recipient_bounce" is not a valid command.
[22:43:26] <magyar_> sysmonk, it's a pain on the arse
[22:43:55] <magyar_> !reject_multirecipient_bounce
[22:43:56] <knoba> magyar_: Error: "reject_multirecipient_bounce" is not a valid command.
[22:44:22] <sysmonk> !learn reject_multi_recipient_bounce as Reject the request when the envelope sender is the null address, and the message has multiple envelope recipients.
[22:44:25] <sysmonk> !reject_multi_recipient_bounce
[22:44:26] <knoba> sysmonk: "reject_multi_recipient_bounce" : Reject the request when the envelope sender is the null address, and the message has multiple envelope recipients.

[23:34:01] <riz_> Hello. I would like the e-mail received with wrong user and/or domain are rejected before rbl check. If I invert the order of rules in main.cf I can't send e-mail.  This is a piece of main.cf http://pastebin.com/m1ea63a91
[23:35:04] <Toerkeium> "The default_destination_concurrency_limit parameter (default: 20) controls how many messages may be sent to the same destination simultaneously" <--- what's the meaning of "destination" there? a smtpd daemon? email address? anyone knows?
[23:39:09] *** havvg has quit IRC
[23:40:27] <adaptr> yes
[23:40:31] <adaptr> I know
[23:41:16] <Toerkeium> adaptr: share with poor people
[23:41:27] * Toerkeium is poor
[23:41:47] <devdas> IP
[23:41:52] <adaptr> a destination is the next-hop MTA deduced from an MX record or directly specified in the config
[23:42:02] <Toerkeium> aha
[23:42:11] <adaptr> in any case, an IP address with a breathing SMTP server
[23:42:32] <adaptr> not a Kenny
[23:43:33] <Toerkeium> do you know a parameter to limit all oubound smtp connections? not a per-xxx limit?
[23:43:46] <Toerkeium> I've been reading the postfix docs, but I can't find it
[23:43:55] <devdas> maxproc in master.cf
[23:43:59] *** mrnotproper has quit IRC
[23:44:03] <adaptr> set whatever limit you require in master.cf, obviously
[23:44:13] <adaptr> damnfucker! stop being 3 seconds in front of me!
[23:44:19] <Toerkeium> won't that limit all (even incoming) connections?
[23:44:23] <adaptr> at least I can writ ea full sentence :)
[23:44:30] <Toerkeium> lol
[23:44:31] <devdas> no
[23:44:38] <devdas> Only smtp processes
[23:44:42] <adaptr> Toerkeium: learn what master.cf does
[23:44:44] <devdas> Avoid modifying the smtpd line
[23:45:09] *** j_s has quit IRC
[23:46:11] <Toerkeium> ah, one will be the smtp client (smtp      unix  -       -       n       -       -       smtp) and the other the server (smtp      inet  n       -       n       -       -       smtpd) right?
[23:46:27] <adaptr> !master
[23:46:28] <knoba> adaptr: "master" : http://www.postfix.org/master.5.html
[23:46:36] <adaptr> all is explained
[23:46:40] <Toerkeium> thanks
[23:46:43] <Toerkeium> gonna read it

[23:47:21] <Toerkeium> I was reading the tunning, but when I thought I got it... hmm, well I didn't.. :)
[23:47:35] *** radius has joined #postfix
[23:48:11] <adaptr> most people never need to adjust these settings, and having to tune before you even know how it works always makes me suspicious
[23:48:42] <adaptr> but then, sunrise makes me suspicious - hell, birds chirping make me suspicious, devious bastards!
[23:49:51] <Toerkeium> well.. it's for a particular customer which will send a newsletter, and want to adjust the outoing limit, but I want to let the customer send all its mails for once
[23:50:15] <Toerkeium> if I let him 100 processes, he will eat my bandwidth
[23:50:26] <Toerkeium> 100 procs/sec I ment
[23:51:25] <adaptr> he can eat your bandwidth on 1 per second, too
[23:51:38] <adaptr> bandwidth limiting is not a function ofan application protocol - it never is
[23:51:50] <Toerkeium> he will send small messagess
[23:52:00] <adaptr> that's what he told you , he ?
[23:52:24] <Toerkeium> messages are just html hosted on another provider
[23:52:28] <Toerkeium> so it's just some html code
[23:52:33] <Toerkeium> from a football team
[23:52:53] <adaptr> hosted HTML ? so all he really needs to send is a URL ?
[23:53:24] *** hparker has quit IRC
[23:53:25] <Toerkeium> well, no. he will send the html in the message (some images and some text), but images will be hosted on another machine
[23:53:28] <Toerkeium> another provider
[23:53:29] <adaptr> (hosted HTML is sometimes referred to by techies as a "web site" - crazy world, eh? )
[23:53:53] <Toerkeium> lol, yes, it's crazy....
[23:53:57] <Toerkeium> and expensive, eh?
[23:54:05] <adaptr> not really, why ?
[23:54:49] <Toerkeium> I like good stuff, they are always so expensive.. or well.. I could have a bad salary, depends the point of view
[23:55:47] *** m0f0x has quit IRC
[23:56:35] <adaptr> what does that have to do with... anything ?
[23:56:44] <adaptr> postfix doesn't cost any money
[23:58:01] <Toerkeium> ahh, well.. I was just not talking about postfix when I said "expensive" referring to the "world"
[23:58:04] <Gershwin> I think he was trying to come up with different lyrics to Sir-Mix-A-Lot's "I Like Big Butts"
[23:58:29] <Toerkeium> what's a butts?
[23:58:49] <Gershwin> It's a song from about 10 or 15 years ago
[23:59:12] *** mschiff has joined #postfix
[23:59:41] <rob0> I think that refers to the non-burning part of a cigarette.
[23:59:54] <Toerkeium> heh
[23:59:55] <Gershwin> :)
