[05:37:22] <heraclitus> what am I doing wrong with my postfix config here? https://paste.fedoraproject.org/310067/14526596/ I want to be able to relay to any and all outside MTA domains and I can't relay to any in my current configuration, I've decided to permit ALL in smtpd_client_restrictions, that overrides the permis_sasl_authenticated and permit_mynetworks parameters. Any hints?
[05:38:55] <tharkun> !tell heraclitus openrelay
[05:38:55] <knoba> heraclitus: "openrelay" : An open relay is a mail server that is set up incorrectly and accepts and forwards mails for strangers. It will quickly be identified and abused by spammers, then blacklisted. Postfix has numerous protections against becoming an open relay, so it is not likely to have this problem.
[05:39:34] <heraclitus> I do not want to be an open relay, just simply be able to send mail to outside domains from my domain
[05:40:10] <tharkun> !tell heraclitus showconfig
[05:40:10] <knoba> heraclitus: "showconfig" : when asked to provide your config, pastebin postconf -nf and postconf -Mf. if your version is too old for those commands to work (< 2.9), you should upgrade, but see !showconfig_old
[05:40:31] <heraclitus> I'm *very* new to MTA, and I'm learning it's quite a rabbit hole for learning
[05:40:34] <heraclitus> wait one on the config
[05:41:46] <heraclitus> I can only output 'postconf -n'
[05:42:15] <tharkun> !tell heraclitus showconfig_old
[05:42:16] <knoba> heraclitus: "showconfig_old" : for versions of postfix < 2.9, pastebin postconf -n and the contents of master.cf with comments removed
[05:42:55] <heraclitus> already posted that in that fedora pastbin
[05:42:58] <heraclitus> :/
[05:43:07] <heraclitus> https://paste.fedoraproject.org/310067/14526596/
[05:44:26] <heraclitus> first line is the relay error, the other lines are labeled by associated file
[05:44:47] <heraclitus> that's the output of 'grep -v -e ^# -e ^$ /etc/postfix/master.cf /etc/postfix/main.cf >> postfix_errors.txt
[05:46:14] <rob0> Fortunately smtpd_client_restrictions does not control relaying. :)
[05:46:22] <rob0> !relay_denied
[05:46:22] <knoba> rob0: "relay_denied" : NOQUEUE: reject: RCPT from CLIENT_HOST[CLIENT_IP]: 554 5.7.1 <RECIPIENT@RCPT_DOMAIN>: Relay access denied; from=<SENDER@SENDER_DOMAIN> to=<RECIPIENT@RCPT_DOMAIN> proto=ESMTP helo=<HELO>: This typically means that CLIENT_IP is not in mynetworks (and did not AUTH), and that RCPT_DOMAIN was not recognized as one of this Postfix's domains (not listed in mydestination, relay_domains or virtual_*_domains).
[05:46:36] <rob0> !sasl
[05:46:36] <knoba> rob0: "sasl" : SASL is 'Simple Authentication and Security Layer', necessary for SMTP AUTH, and provided to Postfix by addin software. Cyrus SASL and/or Dovecot IMAP/POP3 can provide SASL. See http://www.postfix.org/SASL_README.html for details.
[05:47:26] *** lucascastro has quit IRC
[05:47:37] <rob0> "mydestination = *", where did you see that documented?
[05:48:40] <rob0> (Which here means, no, it's not documented anywhere, which further means, no, it does not work.)
[05:49:27] *** marigeo has joined #postfix
[05:51:10] <heraclitus> of course, that was a naive assumption on my part, rob0. I reiterate, I'm new to postfix+dovecot :) I'm quite familiar with most other common protocols and services running on linux, but not MTA.
[05:53:13] <pj> heraclitus: mail servers are a world apart in complexity to other services.
[05:53:36] <heraclitus> I'm noticing :)
[05:53:55] <heraclitus> and my apologies for my naivette.

[13:14:04] <Zerberus> Diplomat: postfix chrooted?
[13:14:13] <Diplomat> nope
[13:14:59] <Zerberus> but your Postfix has no idea about proper name resolving
[13:15:42] <Diplomat> Hmm.. I don't think it's chrooted. How do I know that it's chrooted?

[13:27:24] <Zerberus> read and comprehend your master.cf
[13:29:39] <Tuxick> why would master.cf be aware of chrootedness?
[13:30:03] <Tuxick> ah nevermind :)
[13:30:11] <Diplomat> Meh, it was chrooted
[13:30:53] *** Haudegen has joined #postfix
[13:30:55] <Tuxick> a decent OS would make sure things won't break on that
[13:31:07] <Tuxick> so what did you overlook?
[13:31:30] <Diplomat> Configuration mistake
[13:32:10] <Diplomat> But I'm thinking.. would it be possible to use one DNS server for senders and one for receivers ? Because I can't check for sender domain exist using my internal DNS
[13:32:22] *** Quadro has quit IRC
[13:32:28] <Tuxick> fix internal dns?
[13:32:30] <Diplomat> and if I'd use a public DNS server it would become an open relay
[13:32:35] <Tuxick> huh?
[13:32:59] <Diplomat> Sender -> Proxy -> SMTP relay -> Receiving server
[13:33:09] <Tuxick> i use bind with split views
[13:33:31] <Diplomat> but if my smtp relay would resolve someones yahoo email then my server would send an email to that yahoo email
[13:33:35] <Tuxick> so one dns to rule them all
[13:33:51] <Tuxick> uhm yes, isn't that supposed to be?
[13:34:05] <Diplomat> i'd like to allow only those domains that are in my own dns server and reject others
[13:37:29] *** maziar has joined #postfix

[13:42:27] <Nit_> s/proper/cleaner/
[13:42:36] <Diplomat> In my situation, no since I don't have control over email accounts.. that control is in receiving server
[13:43:12] <Tuxick> now i'm even more confused
[13:43:40] <Tuxick> some weird assumption must have sneaked in
[13:43:49] <Tuxick> !goal
[13:43:50] <knoba> Tuxick: "goal" : describe your goal, not what you think the solution is
[13:43:59] <Tuxick> not quite the one i meant

[14:33:19] <Diplomat> Tuxick: got it already
[14:33:52] <Diplomat> But I was wondering is it possible to discard or reject emails during the um.. client <-> server process.. like after client has sent DATA
[14:34:11] <Diplomat> then spamassassin checks and if result is over threshold then it rejects
[14:37:13] <lunaphyte> you'd have to use a milter to reject mail with spamassassin
[14:37:57] <Tuxick> spamass-milter works ok!
[14:38:27] <lunaphyte> thing is though, that's probably a bad idea
[14:38:43] <lunaphyte> rejecting mail because it is spam is too subjective
[14:39:01] <lunaphyte> instead, better to mark it and deliver it to a mailbox
[14:39:08] *** Batch has quit IRC
[14:39:31] <Tuxick> i reject a fair bit of mail
[14:39:47] <lunaphyte> rejecting mail is fine
[14:39:57] <thumbs> discarding isn't.
[14:40:08] <lunaphyte> breaking it up into different "stages" is the responsible thing
[14:40:20] <Tuxick> sure
[14:41:11] <Diplomat> lunaphyte: well i'd like to reject because my server provider could block my access because im sending spam
[14:41:21] <Diplomat> also those emails are not super important
[14:41:22] <lunaphyte> use postscreen, responsible smtpd restrictions, and reject the nasty garbage. then, accept what remains, and use amavis/spamassassin to mark it as such, and deliver it to a given mailbox
[14:42:31] <lunaphyte> this philosophy then precludes any appreciable benefit for use of a milter, which allows some more modularity and separation between the components involved in mail flow
[14:42:59] <lunaphyte> anyway, what is the actual problem, Diplomat?
[14:43:42] <Diplomat> I have it like: [client] -> [server] -> [smtp relay] -> [server]
[14:44:23] <Diplomat> If I accept spam in smtp relay then i might get blocked by the isp.. also my first server is fairly weak to process mail
[14:44:48] <lunaphyte> where is this spam coming from?
[14:45:00] <Diplomat> from the internet
[14:45:03] <Diplomat> lol
[14:45:16] <lunaphyte> why are you taking mail from the internet and then relaying it to your isp?
[14:45:51] <Diplomat> look at that little thing i wrote above.. there you can see how it works
[14:46:01] <Diplomat> client = normal visitor or spammer
[14:46:01] <lunaphyte> dude...
[14:46:08] <lunaphyte> i looked at it
[14:46:11] <lunaphyte> then i asked the question
[14:46:36] <lunaphyte> so obviously, that "little thing" is not an adequate explanation of what is going on
[14:46:36] <Diplomat> I'm relaying it FROM
[14:46:46] <Diplomat> my ISP server
[14:46:50] <Diplomat> to my SMTP relay
[14:47:02] *** edux has joined #postfix
[14:47:52] <lunaphyte> why is your isp server involved? can you not accept your own mail?
[14:47:59] <lunaphyte> perhaps a better diagram would be useful
[14:48:05] <lunaphyte> that one is too vague
[14:48:40] <Diplomat> Hold on I'll davinci a diagram in paint for you
[14:52:48] <Diplomat> lunaphyte: http://i.imgur.com/KqpKhEh.png
[14:53:13] <lunaphyte> which of those servers do you not control?
[14:54:14] <Tuxick> Diplomat: where's the smile?
[14:54:21] <Diplomat> damn, forgot
[14:54:28] <Diplomat> I control all of them
[14:54:37] <Diplomat> well, I have access to them
[14:54:51] <Tuxick> somehow i have a feeling the answer is "submission"
[14:54:57] <Tuxick> but that's a blind guess
[14:55:07] <Tuxick> since problem still unclear
[14:55:16] <lunaphyte> Diplomat: so what are you worried about then?
[14:55:44] <Diplomat> getting blocked by the ISP who can turn off my port 25
[14:55:56] <lunaphyte> where is the isp in this scenario?
[14:56:02] <lunaphyte> it is not on your diagram
[14:56:05] <Diplomat> :(
[14:56:10] <Diplomat> public network owner is my ISP
[14:56:40] <lunaphyte> who owns srv1 and srv2? the isp? do they have access to them?
[14:57:30] <Diplomat> yes
[14:57:45] *** iGeni has quit IRC
[14:57:55] <lunaphyte> why are you passing all of your incoming mail through them?
[14:58:12] <Diplomat> because i have to
[14:58:14] *** iGeni has joined #postfix
[14:58:16] <lunaphyte> why?
[14:59:00] <Tuxick> i've heard of ISPs blocking outgoing 25, a very good thing
[14:59:02] <Tuxick> but incoming?
[14:59:12] <lunaphyte> it's not uncommon
[14:59:18] <Tuxick> prolly not
[14:59:27] <Tuxick> just less likely, i suppose
[14:59:31] <lunaphyte> yeah
[14:59:56] <lunaphyte> it's more to extort the customer
[14:59:58] <Diplomat> Well they are not happy when I send spam to my smtp relay because I'm just proxying from srv1 to smtp relay
[15:00:26] <Diplomat> so when smtp relay accepts spam that means technically i have sent spam from my isp's server
[15:00:33] <lunaphyte> srv1 and srv2 are not mail servers? what software runs on them for mail to flow through them?
[15:01:05] <Tuxick> Diplomat: you're VERY unclear about direction of mail
[15:01:05] <Diplomat> I haproxy them
[15:01:17] <lunaphyte> i see
[15:01:24] <Diplomat> Tuxick, didn't you see my fabulous arrows on that pic ?

[15:05:14] <lunaphyte> Diplomat: perhaps you could make that statment, "technically", but that is completely absurd
[15:05:45] <lunaphyte> are you having an actual problem with your isp regarding this?
[15:06:18] <Diplomat> Well, blocking outgoing (to smtp relay) smtp connections is a problem for me yes
[15:06:28] <Diplomat> I already got blocked few times and their automatic block lasts for 10 days
[15:06:37] <lunaphyte> there is something else going on then
[15:06:50] *** synthroid has joined #postfix
[15:09:35] *** iGeni has joined #postfix
[15:10:59] <lunaphyte> your isp is watching the traffic from the haproxy servers, and if they don't like the traffic leaving the servers going to your mail server, they automatically block you?
[15:12:08] <Diplomat> yup
[15:12:57] <lunaphyte> that is absolutley crazy
[15:13:12] <Diplomat> well they dont block *me* they block the port :P
[15:13:27] <lunaphyte> block the port, where/how?
[15:13:41] <lunaphyte> does mail from the internet stop arriving at haproxy?
[15:14:58] <Diplomat> Check this: http://puu.sh/muauW/7ea7ef2523.png
[15:15:21] <lunaphyte> i see
[15:15:26] <lunaphyte> here's my advice. ditch the haproxy
[15:15:34] <lunaphyte> it's more trouble than it's worth
[15:16:09] <Diplomat> Well, I need to move the mail somehow to internal (private) network
[15:16:38] <lunaphyte> point your mx records to SMTP RELAY
[15:16:58] <Diplomat> smtp relay is not accessible from the public internet
[15:17:05] <lunaphyte> why not?
[15:17:23] <lunaphyte> do you have any public addresses?
[15:17:43] <Diplomat> Only those in the ISP network
[15:18:27] <lunaphyte> but those are not your servers?
[15:18:33] <Diplomat> Hm, maybe I could just change the outgoing port..
[15:18:46] <Diplomat> instead of 25 I'd use 252 lol
[15:18:58] <Diplomat> I think they understand which protocol it is..
[15:19:33] <lunaphyte> are srv1 and srv2 your servers? who set them up? who owns them? are they physical? virtual?
[15:19:50] <Diplomat> They are virtual, technically I own them, but I don't own that network
[15:19:59] <lunaphyte> does the isp have access to them?
[15:20:05] <lunaphyte> meaning, can they access the os running on them?
[15:20:07] <Diplomat> only on network level
[15:20:08] <Diplomat> no
[15:20:10] <lunaphyte> ok
[15:20:28] <lunaphyte> then i have some different advice
[15:20:51] <lunaphyte> encrypt the traffic between srv1/srv2 and SMTP RELAY
[15:21:09] <lunaphyte> if haproxy can do this, then good. if not, get rid of haproxy and replace it with postfix
[15:21:20] <Diplomat> postfix can encrypt it ?
[15:21:24] <lunaphyte> of course
[15:21:47] <Diplomat> I could use a different port too to confuse them
[15:21:50] <Diplomat> lol
[15:22:04] <lunaphyte> your isp is meddling in things that are none of their business. they do not understand some basics concepts involving networking and email
[15:22:16] <lunaphyte> yes, you could do that too, and it would not be a bad idea, in general
[15:22:54] <Diplomat> I could encrypt it with a ssl cert ?
[15:22:58] <lunaphyte> yes
[15:23:28] <Diplomat> hmm
[15:24:22] <Diplomat> haproxy can encrypt it too
[15:24:36] <Diplomat> nice
[15:25:22] <Diplomat> Ok so I use my public key with my haproxy and private key with postfix and it should work ?
[15:26:14] <lunaphyte> in so many words, yes
[15:26:33] <Diplomat> ok sweet, ill try it
[15:26:38] *** Poster has joined #postfix
[15:26:39] <lunaphyte> configure postfix to present a cert to clients.
[15:27:00] <lunaphyte> when haproxy connects, it will be given the cert by postfix. the cert contains the public key
[15:27:27] <Diplomat> lol it's like some spy shit
[15:27:40] <lunaphyte> eh, not really :)
[15:27:45] <lunaphyte> just encryption
[15:27:54] <lunaphyte> pretty pedestrian
[15:29:07] <Diplomat> Hmmmmmm.. postfix will reject eveyone who don't have the key ?

[15:47:01] <Diplomat> Ah, that's why it accepted my emails lol
[15:47:04] <Diplomat> I thought wtf

[15:47:34] <lunaphyte> set that to 1
[15:48:23] <Diplomat> Hmm.. but you know, people are connecting using helo not ehlo
[15:48:36] <lunaphyte> that shouldn't matter
[15:48:44] <lunaphyte> haproxy is the one connecting to postfix
[15:49:08] <Diplomat> but haproxy is just a tcp proxy
[15:49:36] <lunaphyte> oh, i see
[15:49:44] <lunaphyte> then install postfix
[15:50:56] <Diplomat> I don't know how to proxy it to my smtp relay that way
[15:51:01] <Diplomat> Gotta google
[15:51:06] <lunaphyte> you won't proxy it
[15:51:39] <lunaphyte> postfix on srv1 and srv2 will accept mail, and then relay it to SMTP RELAY
[15:52:12] <Diplomat> well yes, i'm not sure how to do it
[15:53:45] <Diplomat> oh just relayhost = smtp_relay:port ?

[16:25:52] <patdk-wk> didn't know it could even do a lookup via dn
[16:26:11] <car> :)
[16:26:29] <patdk-wk> your lookup is not looking up dn
[16:27:00] <patdk-wk> since you leave out all needed info
[16:27:10] <patdk-wk> it looks like your attempting to do an alias lookup in there
[16:27:15] <patdk-wk> why would you return uid?
[16:27:17] <car> i know its looking up UID, because the group the UID attribute
[16:27:20] <patdk-wk> uid is not a valid result
[16:27:57] <car> the group has the attribute UID , not DN
[16:28:12] <patdk-wk> heh?

[17:19:06] <vvassilev> Hi all. I have a smarthost config. The main server sends mails just fine. The forwarding seems to be unable to connect to its relayhost. I was wondering how I can assert that this is the issue...
[17:21:12] <lunaphyte> !tell vvassilev getting_help

[17:21:38] <vvassilev> !relevant_logs
[17:21:38] <knoba> vvassilev: "relevant_logs" : Relevant logs are mail.* syslog Postfix logs (NOT verbose, see !verbose) which show the entire handling of a single mail which illustrates the issue with which you want help. Random selections from your mail log might not do. IMAP/POP3 daemons and external delivery agents typically log to the same facility (mail); those are usually not relevant here.
[17:21:58] <vvassilev> knoba: !verbose
[17:22:07] <vvassilev> !verbose
[17:22:07] <knoba> vvassilev: "verbose" : You probably do not need verbose logging, but in rare cases the extra detail can assist in debugging. To set verbose logging add a -v after the command name (such as smtpd) in master.cf, then 'postfix reload' after that.

[17:36:06] <vvassilev> phreebird: it is empty...
[17:36:44] <vvassilev> The only piece of log I see is this: connect to mx1.solid-consult.com[80.80.139.116]:25: Connection refused
[17:37:13] <phreebird> is postfix running on mx1?
[17:37:49] <phreebird> And is 25 open on the firewall
[17:37:53] <phreebird> of mx1
[17:38:15] <vvassilev> Yes. I don't understand why mx1.solid-consult.com resolves to 80.80.139.116 and not to the internal address. I have the setting in /etc/hosts and /var/spool/postfix/etc/hosts
[17:38:58] <vvassilev> It is not open, it should relay the mail to the internal posfix, which works fine.

[17:42:53] <phreebird> So postfix wont use the host file at all?

[17:45:45] <lunaphyte> yes
[17:46:14] <vvassilev> Still not good. The queue is empty but no mails sent, none received in the relayhost...
[17:46:30] <lunaphyte> phreebird: postfix can be forced to use the hosts file. however, consider there is a reason why this is not the default ;)

[18:01:46] <phreebird> mynetworks = 127.0.0.1, *proxyip*
[18:02:09] <phreebird> that will alow relay access
[18:02:16] <vvassilev> mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
[18:02:22] <rob0> !nologs
[18:02:23] <knoba> rob0: "nologs" : Nothing in your mail logs commonly means one of two things: either your syslogd is broken (try restarting it), or the connections are not coming to your server. Check your firewall/networking and the DNS for the domain in question. also see !logs.
[18:02:35] <phreebird> at the end of that, add in your proxyip
[18:02:41] <lunaphyte> mynetworks is not the proper way to do that
[18:02:58] <vvassilev> phreebird: sorry misunderstood. Let me check the config on mx1
[18:03:12] <phreebird> lunaphyte: How would you do it then, i have a similar setup
[18:03:21] <rob0> And no, having a relayhost in mynetworks is a recipe for disaster.
[18:03:26] <lunaphyte> [12.00.08] lunaphyte: use smtp auth. not mynetworks
[18:03:48] <rob0> The relayhost is accepting YOUR mail for relay.
[18:04:11] <rob0> If you'll reciprocate that, you could get a mail loop.
[18:04:28] <vvassilev> phreebird: mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 on mx1
[18:04:46] <phreebird> vvassilev: Don't change anything. i'm very wrong apparently haha.

[18:05:12] *** synthroid has joined #postfix
[18:05:18] <lunaphyte> allowing relaying,submission, etc based on source ip address is never a good idea
[18:05:33] <vvassilev> phreebird: undestood.
[18:05:47] <lunaphyte> it is only a *tolerable* idea, if there is some actual reason why it cannot be done the right way
[18:06:36] <phreebird> So you'd setup SMTP auth on mx1
[18:06:45] <phreebird> and configure SASL on the relayhost
[18:06:53] <phreebird> That would be correct?
[18:06:58] <lunaphyte> yes.
[18:07:08] <lunaphyte> pki authentication would be acceptable as well
[18:07:18] <phreebird> I have configuration changes to do then.
[18:07:44] <lunaphyte> if it's not always a work in progress, then you're not making progress :)
[18:07:54] <vvassilev> lunaphyte: I managed to relay the mail the way I wanted. So the initial suggestion in specifying the ip worked. The havoc was caused by me not using sendmail correctly + aggressive spam filtering in the relayhost.
[18:08:14] <vvassilev> lunaphyte: and phreebird thanks a lot for the help.
[18:08:25] <vvassilev> rob0: I will have a look at the logging thingy!
[18:08:26] <phreebird> vvassilev: You're going agaisnt best pracitices
[18:08:38] <rob0> Even then (if some client cannot use AUTH for some reason) it's better to use check_client_access. The mynetworks/permit_mynetworks feature no longer seems like a good idea in 2016 as it did in the 1990s.

[18:10:06] <phreebird> Hmm.
[18:11:46] <phreebird> So SASL Auth is just basically acting as a mail client to relay?
[18:13:59] <lunaphyte> i can't parse that
[18:14:09] <phreebird> Hmm.
[18:14:21] <phreebird> How could i create credentials for my relay host?
[18:14:49] <lunaphyte> the same way you create credentials for other things that need credentials

[20:46:31] <r1ppa> trying to whitelist a domain or emails so that amavisd scanning is skipped, read some docs and wrote this..I see "matches" in the logs but still gets banned due to zip content, will the banned override the whitelist ? my example "map { $whitelist_sender{lc($_)}=1 } (qw(site.example.com));"
[20:46:44] *** heroux has quit IRC
[20:47:09] <jaybe> sounds a lot like an amavisd-new question
[20:47:27] <r1ppa> indeed it is
[20:47:44] <r1ppa> but postfix folken are smarter than the average bear, so why not ask here
[20:47:58] <jaybe> ;)

[21:57:24] <doubletwist> Is there a postfix equiv of "keep_malformed" in exim?
[21:57:51] <rob0> perhaps explain what that does?
[21:58:17] <doubletwist> specifies the length of time to keep messages whose spool files have been corrupted in some way. This should, of course, never happen. At the next attempt to deliver such a message, it gets removed. The incident is logged.
[21:58:53] *** Haudegen has quit IRC
[21:58:59] <rob0> spool, meaning queue, in Postfix terms?
[21:59:12] *** synthroid has joined #postfix
[21:59:36] <doubletwist> Not entirely sure
[22:00:21] <rob0> I'd think so, because only messages in the queue are having delivery attempts.
[22:00:50] <rob0> Maybe poke around "man qmgr" and see what settings there are.
[22:00:57] <doubletwist> ok
[22:00:58] <doubletwist> thx
[22:01:31] <rob0> I recommend the HTML version, qmgr.8.html, because that will have those settings hyperlinked to postconf.5.html

[23:32:31] <dimitry7> Hi guys. I have been blocked in CBL and the reason abuseat.org gives me is this: This IP is infected with, or is NATting for a machine infected with TrojanDownloader:Win32/Ponmocup.A (Microsoft).
[23:32:32] *** Toerkeium has joined #postfix
[23:32:46] <dimitry7> but I have debian installed, it doesn't make sense to me.
[23:33:56] *** trepatudo has joined #postfix
[23:36:02] <doubletwist> I'm using relay_domains and relay_recipients to direct a couple domains to common 'local' mailboxes via Cyrus lmtp. But is there a way to catch "postmaster at one dot example.com" and "postmaster at two dot example.com" before they get relayed to cyrus?
[23:36:54] <doubletwist> Rather, I'm sure there is, but not sure what the appropriate way might be
[23:37:20] <doubletwist> Since it doesn't get caught by the alias in /etc/aliases.
[23:37:47] *** dstarh has quit IRC
[23:38:07] <rob0> dimitry7, and you're not doing NAT for a compromised Windows machine on the same IP address?
[23:38:10] *** afics has joined #postfix
[23:39:02] <dimitry7> rob0, Just one windows servers, the rest of servers are Linux Debian and they use exim
[23:39:48] <dimitry7> rob0, is there a way to find out the originating IP?
[23:40:26] *** trepatudo has quit IRC
[23:40:29] *** pti-jean_ has quit IRC
[23:42:24] <rob0> block Windows from getting out on port 25. Logs attempts in your firewall, which is likely to be an overwhelming amount of logs in short order.
[23:42:46] *** afics has quit IRC
[23:43:49] <dimitry7> rob0, all right, let me do it right away
[23:44:44] *** afics has joined #postfix

[23:45:55] *** trepatudo has joined #postfix
[23:48:20] <dimitry7> rob0, done man!
[23:48:30] <dimitry7> should I request the removal?
[23:51:34] <rob0> no, they'll do it quickly anyway
[23:51:49] <rob0> but it might be nice to tell them it's cleaned up
[23:52:02] <rob0> (did you find the offender?)
[23:52:54] <thumbs> rob0 often offends me
[23:53:06] <dimitry7> rob0, all right, I will tell them then. No, I had my LAN natted, but only a 2 windows servers relayed email. I will run a scan in both to see who's to blame :S
[23:53:25] <rob0> something on the LAN, most likely.
[23:58:31] <dimitry7> rob0, yeah, let's wait for what they say
[23:58:34] <dimitry7> thank you rob0 !!
