<0> what does FAIL (in reply to RCPT TO command) mean?
<1> does anyone here know of/recommend any anti-spam/anti-virus solutions aside from amavisd or dspam? Heck, do any exist aside from dspam that don't just base themselves on spam******in and amavis?
<2> what's wrong with spam******in?
<1> well, for starters, I'd like something that isn't perl :)
<0> all my mail is saying "FAIL (in reply to RCPT TO command)" what does this mean?
<1> dspam looked promising, but I just kept having all sorts of weirdness with it and wasn't able to get it working properly ... I may give it a shot again, but I was curious if there were other alternatives
<3> http://jimsun.linxnet.com/misc/postfix-anti-UCE.txt and greylisting, I use sqlgrey.
<1> basically kinda rolling your own?
<3> Builtin Postfix capabilities, actually.
<1> I already use a few blacklists, though I'm not really wild about using any more than that
<1> ultimately I'd like a way for each user to train the filter for themselves, which I can do with dspam (even if I have problems with their webui), but ... I dunno. I'm going to give it a shot again.
<3> HELO checks? That still takes out roughly 25% of all connections, spammers that HELO with your IP or domain.
<1> no, not using that I don't think :)
<1> that's a long document, so I need to read through all of it hehe
<3> It's a great bargain, to block 25% at the cost of a single PCRE lookup.
<1> hehe
<3> No DNS queries if you place it right. I even do the HELO check before reject_unauth_destination.
<4> My ISP's being a bastard, so I can't use the standard port 25. Is there a way for other mailservers to reach me (so that my mail can come in and out) on a non-standard port?
<3> nope, you absolutely must have SOME place receiving mail for you on 25, somewhere. I used to do a relay for a friend of mine, I was the MX and I forwarded it to his server on an alternate port.
<4> rob0, What about smtp over ssl?
<4> rob0, Will that automatically be detected by other servers, since that is a standard port?
<3> no.
<4> crap...
<4> How do I lookup the MX record of an email server? My company uses non-standard ports, so, I'm trying to see if I have control of the relay server.
<4> Wha...
<5> hey you guys... how do i keep non-local mail from being delivered to my mail user?
<4> That's strange... how does my company's mail get delivered? There's no smtp server on port 25 where the MX record points to.
<6> maxdoubt, check mydestination
<6> RobBarton, port forwarding?
<4> keanne, Perhaps... but when I connect on port 25, there's nothing there.
<4> keanne, smtps is open.
<6> RobBarton, there's your answer then
<6> RobBarton, and maybe you will be in trouble when your admin finds out that your port scanning the server :)
<4> keanne, Heh. I'm the SysSec. He can go to hell.
<6> SysSec? what's that?
<4> keanne, Systems Security.
<5> keanne: sorry... how would i do that w/ mydestination... i have it set for the domains for which postfix should receive mail right?
<6> hmm...must be a big orgranization, having those two functions seperately in the org
<6> maxdoubt, yes. but your question is, how to make non-local mail delivered to your mail user. so what is this non-local mail?
<5> just some spam
<4> keanne, Heh. Small. But... let's say our last SysAdmin wasn't so happy with his conditions of leaving.
<6> duh, i misunderstood you
<5> but ideally, nothing from the outside world should be delivered to my mail user
<6> maxdoubt, why?
<5> cause the only mail going to my mail user should be from the server on which postfix is running
<5> like system logs and stuff
<6> RobBarton, ok, so your using smtps, that is some security measures
<6> maxdoubt, deny it then
<5> well, i guess that's what i'm asking how to do... i just thought it'd be easier to deny all non-local stuff?
<5> sorry if i'm being green about this
<4> keanne, Hmm... weird. I just configured my server to use TLS, but it's still listening on 25.
<6> maxdoubt, although i havent tried it, you can use restriction cl***es.
<6> maxdoubt, this will give you some idea. http://sbserv.stahl.bau.tu-bs.de/~hildeb/postfix/postfix_restriction_cl***es.shtml
<4> keanne, Can you check that encryption is actually working, and I didn't m***ively screw up the config? (o3.ath.cx running on smtps port)
<6> RobBarton, as much as i want to help, technically, that is impossible for me. i don't have a direct internet connection
<4> keanne, It's alright!
<4> Can anyone else lend a hand to a poor mail-newbie in distress?
<5> RobBarton, i would, but i'm running late as it is
<5> not to mention i know very little about postfix, let alone encryption
<5> thanks guys
<4> maxdoubt, It's alright. I'll ask on ##linux, or someplace.
<6> maxdoubt, be very careful then, exposing your server to a channel mostly full of capable people of doing nasty stuff is scary to me
<5> keanne, thanks for the concern... hopefully somebody hacks into it and realizes that its just for booking concerts, and maybe we'll actually pull in an audience that way
<3> TLS does use 25.
<4> keanne, Heh... Can you use SSH?
<7> I suddenly started getting a lot of errors in /var/log/mail.err and /var/log/syslog, fatal: gethostbyname: Resource temporarily unavailable
<7> AFAIK nothing changed...
<6> RobBarton, hmm..ok, i will try to tunnel SSH through http proxy, but you have to supply me your IP and not your FQDN
<4> keanne, Sure!
<8> RobBarton: which port would you like postfix to listen on?
<4> lunaphyte, Fixed that. Onto more issues. :)
<8> checking that encryption is actually working?
<4> lunaphyte, And that I didn't m***ivly screw up my configuration, yeah. :)
<8> your log files can probably answer both of those questions.
<4> lunaphyte, My log files are flooded with dovecot complaining.
<8> grep postfix
<4> lunaphyte, How did I know. It looks fine, but, better check.
<8> increase smtpd_tls_loglevel and submit some mail if you are curious
<7> Hm, found some postfix mailing list posts that suggest it may be a filesystem thing, possibly with too-large files.
<1> question ... I'm trying to get a transport thingy set up (never have used them yet) and have run into a bit of a problem
<1> I have a table called "transports" in pgsql with two columns, id and transport ... my .cf file for transports has select_field = transport, where_field = id
<1> yet if I do postmap -q id pgsql:/etc/postfix/pgsql_transport.cf (where id is obviously the id value) it doesn't match
<1> and I'm not sure why it doesn't :(
<1> any ideas?
<1> if I go into psql and do "SELECT transport FROM transports WHERE id = 'id'" it returns the transport field as it should
<6> MysticOne, have you made it to work *without* using SQL maps first?
<6> i mean SQL lookups
<6> you do not have to postmap pgsql_transport.cf too
<6> and tell us why doesnt work with transport_maps
<1> keanne: err, wait, what? :) No to the first part, I don't understand what you mean on the second part
<6> i mean what
<1> well, I'm trying to make it so that when a message comes in destined for spam@foxybanana.com, it's handed off to a script (I already set all that up, though don't know if it works yet)
<1> when a message comes in for spam@foxybanana.com, it gets bounced
<6> have you tried transport_maps using hash lookups first?
<1> no, let me finish though
<6> to a script? you have to use alias
<9> we host sites with a peel? AUGH.
<6> not transport_maps, afaik
<1> so, I checked to see if the address matched when using postmap -q spam@foxybanana.com pgsql:/etc/postfix/pgsql_transports.cf, and it doesn't match
<1> mendel: I know, it's supposed to be cheesy :)
<9> :D
<6> MysticOne, use alias
<1> keanne: what will I point it to?
<6> MysticOne, considering your domain is foxybanana.com, add spam:"|/usr/local/bin/your.script.pl"
<6> put that in your alias file
<1> hmmm...
<1> all the examples I've seen so far suggest using transports (with dspam)
<1> so, why would it be one over the other?
<1> I still don't fully understand transports
<6> transports have mappings of "foo@domain transport:nexthop" so i fail to see why to use transport_maps, but it maybe me that is used to use alias for piping mails to scripts
<1> I have spam@foxybanana.com and that goes to dspam-retrain:spam
<1> and then I have dspam-retrain set up in master.cf
<6> oh, that should work
<1> except that I'm back to the problem of why it isn't matching lol
<6> maillog
<6> we need to see the logs :)
<1> no errors
<6> about the bouncing part
<1> I figure if it isn't going to match with postmap -q, it's not going to map from within postfix either
<1> bounces and says unknown user (even though there is no user, it's a transport and not a user)
<1> ahhh, I figured it out
<1> does the order of items in main.cf matter?
<1> okay, related question, but different machine (with an older version of postfix) ... transport > virtual mailbox, right? If there's an address listed as a transport, it should be considered and matched before a virtual mailbox, shouldn't it?
<10> Hi
<11> hih0
<12> Hi.. Just to help my evaluations What are the big advantages of postfix over qmail, besides the licensing thing?
<13> you like dags
<12> dags? sorry my english is not so good :)
<12> lawnchair: What did you mean?
<3> qmail is dead. Its fanatics have yet to figure that out, but I don't think it's worth taking seriously these days.
<12> rob0: huh? :)
<13> heh
<3> http://www-dt.e-technik.uni-dortmund.de/~ma/qmail-bugs.html
<12> Okay, if that could be proven on activity in the qmail channel then you probably are right, rob0 ;)
<12> Is there a website like qmailrocks.org for postfix? a really high-detailed how-to?
<3> I have extensive experience in both. Most people I've found who know enough about both seem to agree with me.
<3> www.postfix.org has extensive documentation, all of it included in the source tarball.
<3> !basic
<14> rob0: 'basic' : http://www.postfix.org/BASIC_CONFIGURATION_README.html : a good starting place for Postfix beginners, many common questions are answered here.
<12> rob0: yeah sure, but I like a more how-to like tutorial - its gonna be my first installation of a MTA
<12> rob0: Right now the qmail people tell me the same, qmail is dead, now there is http://netqmail.org/
<3> There's a lot of it all hyperlinked in your $html_directory. Did you already read BASIC_CONFIGURATION_README ?
<12> yeah sure.. but I want more "why is that like it is" information ;)
<3> The default main.cf comes with useful comments. When I set up my first Postfix that was all I needed.
<12> rob0: I want to set up a MTA with virtual accounts or however it is called.. I mean without add system users
<3> http://www.postfix.org/docs.html links numerous HOWTOs and external resources.
<3> Just curious, why is that?
<3> !virtual
<14> rob0: 'virtual' : a way to configure additional domains and user accounts (that do not need to exist in your /etc/p***wd). See: http://www.postfix.org/VIRTUAL_README.html
<12> rob0: Without mySQL?
