I have installed postfix and dovecot and it is working fine. Just a doubt regarding the sending of mails to users[19:20:38] *** davlefou_ has quit IRC[19:21:18] <wrod> if someone is aware of incoming and outgoing settings of my domain. Can he configure his mail client to spam my domain users ?[19:22:00] <wrod> smpt auth is for allowing relay mails or can it be for even local mails ?[19:22:30] <lunaphyte> not sure what you mean by "local" mails.[19:22:39] <lunaphyte> smtp auth is for submitting email to an msa.[19:22:44] <wrod> I mean for local users[19:23:19] <lunaphyte> what about them?[19:23:25] <lunaphyte> what is a "local user"?[19:23:45] *** me__ has quit IRC[19:24:34] <wrod> ok. I mean can someone configure his mail client outgoing as my smtp server and spam my domain users . I have configured smtp auth[19:24:57] <lunaphyte> one has nothing at all to do with the other.[19:25:17] <wrod> but i believe that is working only if a user want to relay his mails to another domain[19:25:29] <lunaphyte> huh?[19:25:49] <lunaphyte> if someone wants to connect to your server and deliver mail to your users, of course they can do that. if they couldn't, how could you ever receive any email from the internet?[19:26:01] <lunaphyte> that's got nothing to do with submission though.[19:26:58] <wrod> ok. So if such a user is aware of all mail address of my domain I would not be able to restrict him if he has configured his outgoing smtp to be my mail server ?[19:27:43] <lunaphyte> why would anyone configure their outgoing mail server to be your mta?[19:28:01] <lunaphyte> unless you were an open relay, that wouldn't make any sense, even for a spammer.[19:28:15] <wrod> suppose it is an ex employee who has resigned[19:28:48] <lunaphyte> a disgruntled ex employee?[19:29:31] <wrod> yes you are right.

But this user could be hitting my mail server directly[19:29:32] <lunaphyte> and what sort of restriction would you like to impose?[19:29:55] <lunaphyte> i don't know what "I have spamassassin running on my mx server. But this user could be hitting my mail server directly" means.[19:30:08] <lunaphyte> maybe you are assuming we know more about your configuration than we do?[19:30:44] <wrod> for spam mails from internet i have spamassassin to filter the mails on my MX server[19:30:46] *** steven4455 has quit IRC[19:31:01] <lunaphyte> of what relevance is that?[19:31:44] <wrod> but I am not able to understand how I could stop any disgruntled user from hitting my smtp server directly.[19:31:47] <thumbs> wrod: perhaps you should take a step back.[19:31:58] <lunaphyte> you cannot stop any disgruntled user from hitting my smtp server directly[19:32:01] <thumbs> !tell wrod overview[19:32:02] <knoba> wrod: "overview" : Postfix Architecture Overview : http://www.postfix.org/OVERVIEW.html[19:32:13] <lunaphyte> *hitting your[19:32:35] <lunaphyte> how would you propose to do such a thing?[19:33:11] *** haidjin has left #postfix[19:34:19] <wrod> I am not at aware but I thought there could be a way to prevent such an abuse of the smtp server.[19:34:27] <thumbs> what abuse?[19:34:50] <lunaphyte> why are you so worried about this non problem?[19:35:05] <lunaphyte> focus your efforts on fighting spam.[19:35:22] <thumbs> jeebus[19:35:24] <lunaphyte> that is an actual problem.[19:36:01] <wrod> ok. So far I have faced this issue but I was thinking ahead. Maybe I am too paranoid[19:36:13] <lunaphyte> you will likely find that as you become more adept at fighting actual spam, a side effect will be that many of these other pretend problems magically go away[19:36:37] <wrod> ok, thanks for your inputs[19:37:15] <lunaphyte> on that note, i hope you have a proper submission service set up, properly separated from your mx service.[19:38:00] <thumbs> lunaphyte: don't be so sure :([19:38:08] <lunaphyte> :)[19:38:27] <lunaphyte> my hope rarely reflects my expectations :p[19:38:56] <wrod> do you mean smtp auth to prevent an open relay ?[19:39:04] <lunaphyte> huh?[19:39:06] <lunaphyte> i mean what i said.[19:39:13] <thumbs> jeebus[19:39:26] <thumbs> start with the overview.[19:39:49] <wrod> proper submission service set up ?[19:39:58] <thumbs> !tell wrod submission[19:39:58] <knoba> wrod: "submission" : Port 587 is submission, for user submission of mail, NOT suitable for mail exchange.
