[00:02:52] <Diranged> ok so i guess im wondering how i can allow mail relaying to any domain, if a user comes in with a certificate that is signed by the same root CA as our server cert

[00:09:10] <Patrickdk> google it :)
[00:09:57] <Diranged> gee thanks for the help..
[00:10:51] <Patrickdk> well, I dunno what more you want
[00:10:59] <Patrickdk> your asking questions like you NEVER READ A MANUAL
[00:11:13] <Patrickdk> in that case the only answer you will get is read the damned manual
[00:12:21] <Diranged> Patrickdk: Thanks for being a dick about it.. really appreciate that. I am reading that manual, but there are literally hundreds of different possible configuration options depending on what I'm trying to do. I thought that you guys might be able to interpret my goals and help me with the answer a little bit faster than reading that huge ass doc. Apparently not, so thats fine.. I'll go read the doc and figure it out myself.

[00:21:04] <mac-> hey
[00:21:57] <mac-> I wish to give my users my certificate to import into windows what will remove this silly warning from i.e. Outlook
[00:22:48] <mac-> then I should give them this cert which is set as smtpd_tls_cert_file ?
[00:23:16] <rob0> they need the CA cert that signed it
[00:23:23] <Patrickdk> normally
[00:23:29] <Patrickdk> if it's selfsigned, heh
[00:26:22] <mac-> well I gave them cert which is set as smtpd_tls_CAfile
[00:26:30] <mac-> but it didn't work
[00:26:53] <mac-> when send them cert from smtpd_tls_cert_file warning disappeard
[00:27:27] <rob0> did the CA sign the server cert?
[00:27:39] <mac-> no its self-signed
[00:28:00] <rob0> so, you found your answer, I guess
[00:28:06] <Patrickdk> if it's selfsigned how do you have a ca certificate?
[00:28:19] <Patrickdk> or well, something in smtpd_tls_cafile
[00:29:11] <mac-> hmm
[00:29:49] <mac-> is there any windows list of official CAs wher should I add my own CA ?
[00:30:26] <Patrickdk> selfsigned != ca
[00:30:45] <Patrickdk> if you have a ca, then yes
[00:32:36] <mac-> hm well finally I should import both certs - of my server, and of my CA ?
[00:33:08] <mac-> by 'my CA' I undestand this one which I've geberated by myself

[01:03:39] <jiffe98> is it possible to deliver mail based on a field in the message header?
[01:05:21] <adaptr> define "deliver based on"
[01:06:01] <adaptr> postfix routes mail based on the recipient and/or sender address, primarily
[01:07:11] <jiffe98> our mail filter can send a copy of all mail to a specific email address, the message is intact except a couple headers it adds to indicate who the original recipient was, I want to deliver to the local mailbox for that original recipient
[01:07:50] <adaptr> wrong way around
[01:08:07] <adaptr> first split off a copy based on the original recipient, then deliver to the filter

[01:08:17] <knoba> adaptr: "recipient_bcc_maps" : a configuration parameter in the main.cf: Optional BCC (blind carbon-copy) address lookup tables, indexed by recipient address. The BCC address (multiple results are not supported) is added when mail enters from outside of Postfix.
[01:08:45] <jiffe98> this is for incoming mail
[01:08:47] <jiffe98> it hits the filter first
[01:08:49] <adaptr> (no idea why you think yuo need a "custom mail filter" to do that)
[01:08:54] <adaptr> jiffe98: wanna bet ?
[01:09:06] <Patrickdk> I don't get why you want two copies
[01:09:19] <jiffe98> adaptr: the filter is not a box we control, this is before it ever hits our postfix machines
[01:09:21] <Patrickdk> I mean, what happens to the *non* copy?

[14:01:44] <jarr0dsz> if i enter my hostname inside mxtoolbox.com it gives no errors, no open relay
[14:01:47] <jelly> it's... better than using telent

[14:03:21] <jarr0dsz> jelly: okay thanks i look into that
[14:03:51] <jarr0dsz> beside using swaks wich i have to divein, is there a quick way to check why i cannot send mail? telnet session and auth with username password?
[14:04:01] <jarr0dsz> appe mail just gives general error wich is useless
[14:04:26] <jarr0dsz> if i can connect with telnet host 587 and it shows the postfix server then i guess at least the server is running fine and open on port 587 but it could be some auth error
[14:06:02] *** scarleo has quit IRC
[14:06:17] <jarr0dsz> okay perl swaks and then inside the script to i added my info at hostname dot com

[14:08:34] <jarr0dsz> okay great, swaks works sending testmail on the server but not from my local machine
[14:09:02] <jarr0dsz> so its some connection issue swaks says its timing out but strange thing i can do telnet hostname.com 587 and it shows postfix ;s

[14:12:09] <jarr0dsz> but strange thing that is with no authorisation in form of info at domain dot com, and password

[15:18:33] <d3c> what's the probably most lightweight pop3 client that I can use for testing postfix on my dev box?
[15:18:44] <Motafoca> d3c: telnet? :)
[15:18:48] <Motafoca> very light
[15:18:49] <Motafoca> :)
[15:19:14] <Motafoca> my postfix aint creating a log inside /var/log, its uses some other location?
[15:19:22] <d3c> Motafoca: I'd like to be able to connect from a regular mail client, e.g. Safari on OSX
[15:19:38] <d3c> Motafoca: so I'm gonna need a pop3 server, sorry
[15:20:23] <Motafoca> safari is mail client?
[15:20:29] <Motafoca> i tought it was web client
[15:20:34] *** leto has joined #postfix
[15:20:44] <Motafoca> but you can use this simple example
[15:20:49] <Motafoca> if you want to just test
[15:21:06] <lunaphyte_> pop3 should not be used. use imap
[15:21:16] <lunaphyte_> and safari is a web browser, not an email client.
[15:21:35] <lunaphyte_> telnet and/or s_client can be used to test any of smtp, submission, pop3, imap, etc.

[15:22:46] <leto> Hi, I've a "Recipient address rejected: Domain not found" error with postfix. I'd like to bypass recipient verification for this particular domain (that I trust), is it possible?

[15:24:11] <Motafoca> were can i check the sendmail stuff?
[15:25:04] <leto> lunaphyte_: the recipient address is prefix.mydomain.net. It probaly fail because it's an alias/virtual address. That's why I'd like to bypass recipient verification (by a whitelist or similar) in postfix

[15:28:55] <d3c> lunaphyte_: doh, meant "Mail", sorry. isn't pop3 a lot more simple for just testing emails sent by an app via postfix?

[16:24:55] <Dominian> mikunos: what rob0 said

[17:21:57] <rob0> POP3 should have died out 10 years ago. IMAP has replaced it. But perhaps you need neither? You can directly read a maildir or mbox file with any pager.
[17:22:08] <twobitsprite> is this saying there's a configuration error on the remote server, or on mine? if mine, how do I figure out where the error is?

[18:00:35] <Diranged> lets say I have a production mail-sending-farm that sends a few hundred thousand messages a day. everything is DKIM'd properly, and SPFd. the addresses come from @domain.com. Our inbound mial for @domain.com though is passed through either google, or through another mail service. Do I need to allow any inbound mail to these 'mail senders', or will bouncebacks always go through our normal MX records?
[18:02:56] <rob0> hmm? Bounces go to the MX (or A if no MX) of the sender domain.
[18:02:59] <rob0> !example
[18:03:00] <knoba> rob0: "example" : Example.TLD has been reserved for examples in generic top-level domains (com,net,org) and many other TLDs. Please do not use real Internet names as examples.
[18:03:30] <kreign> rob0, domain.com is such a common example use, they should've used domain.com for the RFC. :)
[18:03:50] <rob0> that's why Dotster paid so much to own it
[18:04:02] <patdk-wk> hmm, I can't get enough of people
[18:04:11] <kreign> rob0, domain.com or example.tld?
[18:04:16] <patdk-wk> guy had bad helo name, we had them fix it
[18:04:25] <patdk-wk> they fixed it, but now it has a extra space on the end
[18:04:58] <kreign> rob0, wasn't it a verisign tld at one point?
[18:05:36] <rob0> com is verisign, isn't it?
[18:05:44] <patdk-wk> .com and .net
[18:05:57] <patdk-wk> but domain.com is owned via godaddy I believe
[18:06:05] <patdk-wk> I think dotster is a godaddy thing
[18:06:09] <rob0> no, Dotster is a registrar
[18:06:18] <patdk-wk> oh, a different one?
[18:06:22] <Diranged> ok.. so all bounces will go through our normal MX inbound config, which is good.
[18:06:34] <kreign> godaddy is supposedly shelling out like verisign has due to bad rep
[18:06:47] <Diranged> ok second question then.. is there any benefit to my postfix sender boxes identifying their real public hostnames, or is it reasonable for them to lie and just say that they're "mailer.ourdomain.blah"
[18:07:38] <patdk-wk> I won't accept mail from you, if they don't use real working names
[18:07:43] <kreign> Diranged, I don't see why to not use the real hostnames.
[18:08:02] <kreign> Diranged, if you're only accepting from an MX it's not much consequence...
[18:08:04] <rob0> you definitely must use FCrDNS
[18:08:16] <Diranged> thats what i figured.. and im fine with it...
[18:08:30] <kreign> I need to get SPL working for my stuff.
[18:08:32] <rob0> helo/PTR/A all in agreement
[18:08:39] <kreign> you guys notice much spam drop with it implemented vs. it not?
[18:09:16] *** nowthatsamatt has quit IRC
[18:09:18] <patdk-wk> what is spl?
[18:09:42] <rob0> Diranged might also want to hire a deliverability consultant if problems continue beyond that.
[18:10:02] <rob0> because there is nothing more you can do in Postfix
[18:10:24] <Diranged> heh ok last question about DNS … what if we use CNAMEs instead of A records for our actual mailer servers.. so i have "foo.domain.tld" CNAME for "foo-1235123123.amazon.com". but in amazon, we have them set the reverse PTR record be "foo.domain.tld"?
[18:10:36] <Diranged> or do i need to just go ahead and do an A record for foo.domain.tld that points to our eip..
[18:10:49] <Diranged> (btw, we're not having deliverability problems yet.. trying to head them off by cleaning up alot of things)
[18:10:50] <rob0> definitely not use CNAMEs in mail
[18:10:55] <Diranged> yeah thats what i figured
[18:10:56] <patdk-wk> I don't think cnames are valid
[18:11:00] <patdk-wk> read the rfc's :)
[18:13:02] <twobitsprite> I believe the RFC specifically forbids CNAMES in MX records
[18:14:12] *** d3c has quit IRC
[18:14:54] <kreign> yeah
[18:14:59] <kreign> it will work, I think.
[18:15:01] <kreign> but it's not valid.
[18:15:25] <kreign> (variable definition of "work")
[18:15:33] <twobitsprite> I would't bet on all relays resolving them correctly
[18:15:38] <kreign> good interview question for "mail experts"
[18:15:51] <twobitsprite> I know Domino doesn't like them... ran in to that problem before
[18:16:50] <twobitsprite> ahh, found it: rfc2181 section 10.3 :)
[18:16:54] <patdk-wk> I don't use cnames, so I don't think they are valid :)
[18:17:00] <patdk-wk> been to many years since I looked at the rfc for that
[18:17:09] <kreign> twobitsprite, sweet
[18:17:23] *** wdp_ has joined #postfix
[18:17:34] <twobitsprite> This domain name must have as its value one or more address records. Currently those will be A records, however in the future other record types giving addressing information may be acceptable. It can also have other RRs, but never a CNAME RR.
[18:17:59] <kreign> twobitsprite, i had a guy a while back who could tell me which sections of which RFC certain 'best practices' originate from, but he didn't know anything about actual management/configuration/etc. of general stuff. really odd.

[18:20:26] <kreign> he's pushing all his customers to o365 and the like.
[18:20:58] <kreign> largely because 'their email service is superior'
[18:21:13] <twobitsprite> ugh...
[18:21:20] <kreign> ... because they run postfix, I suppose?
[18:21:30] <twobitsprite> do they?
[18:21:51] <kreign> bigfish = postfix
[18:21:58] <tuxick> i saw zimbra comes with postfix, but i wonder about its performance, anyone run into it?
[18:21:59] <kreign> at least that's what the service ID says.
[18:22:15] <tuxick> i mean the java/zimbra bit, i know postfix works ok :)
[18:22:36] <twobitsprite> weird...
[18:22:46] <kreign> tuxick, I um don't know about the java, but the mail storage/IMAP is dovecot, which works quite well. perf is going to be hardware constricted, not software.
[18:22:55] <kreign> more than likely. ;)
[18:23:36] <rob0> bigfish is Microsoft, no?

[18:26:33] <twobitsprite> true
[18:26:45] <kreign> but yeah, it'll identify on outgoing as postfix
[18:26:48] <kreign> it's not a consistent service.
[18:27:06] <kreign> it works, but to no props go to microsoft...
[18:27:14] <rob0> what IP address was that twobitsprite?
[18:27:49] <twobitsprite> I just did a "nc mail.global.bigfish.com 25"
[18:28:54] <twobitsprite> only 2 servers in that A record
[18:29:01] <rob0> That is definitely not Postfix.
[18:29:11] <adaptr> "IPs". there may be dozens of servers
[18:29:23] <twobitsprite> adaptr: he asked which IP :P
[18:29:26] <rob0> I hit 184.108.40.206 from here.
[18:29:31] <patdk-wk> heh, that is exchange :)
[18:30:10] <adaptr> Exchange exposing itself sounds just as good as "middle-aged pervert"
[18:30:13] <kreign> meanwhile, in Redmond (or somewhere in India), "Metesh, the people in #postfix, they are attacking!"
[18:30:40] <rob0> You can change the banner all you want (not sure why anyone would want to pretend to be MSexchange ...), but you can't change the smtpd behavior without rewriting the source.

[21:12:36] <Dmole> noob question: is there a way to add postfix 2.9 to yum priorities?
[21:12:56] *** krzee has joined #postfix
[21:12:59] <rob0> that would probably be a yum question
[21:13:19] <Dmole> it's more of a "where is the repo" question
[21:13:43] <rob0> and that would be one for #your-distro-here
[21:14:04] <Dmole> not so much
[21:14:26] <rob0> Okay.
[21:14:46] <Dmole> it's not "how to use apt or yum" it's is postfix maintaining a repo for any distro?
[21:14:57] <rob0> No.
[21:15:03] <Dmole> ah thanks
[21:15:27] <Dmole> rpm it is then :(
[21:15:59] <rob0> Simon Mudd maintains SRPMs for Postfix.
[21:16:12] <Dmole> thanks
[21:16:28] <Dmole> 2nd question: is there a page for postfix EOL (end of life)?
[21:16:37] <rob0> yes, the download page
[21:17:53] <Dmole> yes I see it, I guess there was no "End of life" on the page so google missed it
[21:18:12] <Dmole> thanks again
[21:18:41] <rob0> 2.5 was just EOL, 2.6 will be in about a year.
[21:19:44] <rob0> He's going for yearly releases, early in Q1, followed by EOL of the then-oldest supported release.
[21:20:23] <Dmole> I'm still using 2.3.3 on CentOS release 5.7 ~
