<0> I've installed postfix.. and I permit relay to my network 10.0.0.0/24, my client use webmail... but I want to permit to someone to relay only locally... what can I do?
<1> franz: check smtpd_client_restrictions
<0> thanks sanmarcos...
<1> to reject all other than your networks set smtpd_client_restrictions= permit_mynetowrks, warn_if_reject, reject
<1> then smtpd_delay_reject = yes
<1> the postfix faq can be very useful
<1> franz: did it work?
<2> Okay, I've got (among many others) this one relay client that feels the need to send a bimonthly mailing (of a very large .doc file which is a newsletter of some sorts) to a list of a few hundred of their customers and sponsors. Normally I'd just laugh at their stupidity for choking their own bandwidth, but for some reason that I don't want to know the details of, their mail server insists on sending them in parallel.
<2> Meaning that the postfix server I control, which is their smarthost, gets completely and utterly bogged down for as long as it takes them to push every single one of those few hundred very large emails through their puny 1Mbit adsl connection.
<2> So I'm looking for some options that allow per-client throttling (alas, not literal); some way of denying more than, say, four simultaneous accesses per origin IP. Is there something like this in postfix?
<3> Shadur: You mean something like "smtpd_client_connection_count_limit" or "smtpd_client_connection_rate_limit"?
<2> Sounds pretty close to what I need, yes. Lemme look them up.
<2> Looks like that's doing the trick. Thanks.
<4> hello, i'm having trouble sending mails with my mail server, i have this in my logs: http://pastebin.com/525497, could someone point me in the right direction ?
<5> antivirus/spam software broken?
<4> i though about amavis broken, but i have no clue
<6> Is your content_filter running?
<5> is it running?
<4> amavis/clamav are working for receiving mails
<4> f3ew: yes
<5> what happens if you telnet localhost 10024 ?
<4> nevermind
<4> f3ew: amavis wasn't working :(
<4> nevermind
<4> sorry, i feel shame
<4> it's been 30 mins I'm on it
<6> No need to feel asamed
<6> ashamed
<4> have a nice day !
<2> ... We found the client's problem.
<6> hmmm?
<2> Apparently, MS ***Change has an... "interesting" default value for the maximum number of simultaneous outbound connections.
<2> 1000.
<2> And a "slightly" more restrained per-domain limit of a mere 100.
<3> Is that the proof that we have always been looking for that M$ Exchange is more powerful than Postfix?
<2> It's at least the proof (as if we needed more) that someone in MS is very good at taking deep hits of the crack pipe.
<7> hello there - small question - I've got a very simple user table used by postfix (for virtual maiboxes) as in http://workaround.org/articles/ispmail-sarge/ - the problem is that amavis (who needs access to the database... but why ?! to check users ?! it's not its job...) is also querying the db for spam policy fields (like spam_tag_level) which I'd rather like to be in the config files... I never asked amavis to search for those fields !
<8> your amavis descided to do something by its own??
<7> :-) apparently
<8> "computers are getting smarter..."
<8> why do you think its amavis?
<5> "I'm sorry Dave, I'm afraid I can't do that."
<8> maybe it's your header/body_checks in main.cf?
<8> like, header_checks=mysql:...
<7> mjt: it's definitely amavis - I'm upset with this pb, now I dig in amavis sources
<3> CloD: amavis checks the domains to see if you are sending from an internal domain or receiving from an external domain.
<7> ChrisH: ok, that's a good reason - now if I want ONLY domains and not spam policies to be read... ?!
<7> from the db
<3> CloD: IMHO amavis can't do that. The SQL integration in amavisd is a bit... strange. Actually amavis is completely strange but I don't know any decent alternative. :)
<9> heh
<9> It might not be strange, if I could only figure it out. Works good, which is a good thing.
<7> ChrisH: thanks for your humble opinion
<5> ChrisH: trained monkeys?
<10> what could I put in relay_domains = hash:/etc/postfix/relay_domains ?
<3> af_: A red skull key.
<10> I mean I got that: postmap: warning: relay_domains, line 1: expected format: key whitespace value
<10> but I have no key, just a couple of domains
<3> af_: Okay, that's a question I can deal with. :)
<3> af_: The format is "key whitespace value" just as it described. The value can be anything. So the lines look like "domain.com banana-daiquiri" or "domain.com OK" or whatever
<10> oh I see
<10> so that I put just don'matter
<10> thanks
<11> hey, I'm still here. neat
<10> it was easy :)
<3> af_: :)
<11> how do I get the $RECIPIENT env var p***ed through to a program called by procmail through .forward?
<11> p***ing -p to procmail didn't seem to help
<3> af_: Those files usually have a LHS (left-hand side) and RHS (right-hand side) for mappings. But if you just list domains then only the LHS is looked at.
<10> good
<12> I just installed and tested postfix and sent mail to my machine but i don't know where i can find my messages?
<5> jariep1_: postconf mail_spool_directory
<12> ok
<11> nobody?
<11> bah
<11> this is painful
<8> postfix export some environment vars; but i for one don't know how to tell procmail to keep them when running external commands.
<11> that's what -p is supposed to do, according to the manpage
<11> but noooo
<11> that'd be too easy
<13> i'm having trouble getting postfix to work
<13> could someone give me some help with it?
<11> ah, I need to enclose the command in .forward in quotes
<11> obviously :)
<12> if I can send messages to my host without getting them returned does that mean that they are being received by postfix, or can they get lost in transit?
<3> jariep1_: It's very unlikely that mails just disappear. Check your logs to see where they went.
<12> ChrisH, ok
<12> thanks
<9> BoldStrike, where are you stuck?
<13> cpm: not sure really
<13> cpm: just did netstat -ntpl and i don't see port 25 open
<13> cpm: maybe the firewall configuration?
<9> maybe
<9> is postfix running?
<13> when i tried a local telnet to 25, postfix answered
<9> that's a good sign :)
<9> sounds like it works then.
<13> yeah, more than halfway there
<13> just trying to figure out where the snag is
<9> postconf inet_interfaces
<9> ?
<13> all
<13> i've just installed and am starting to use gnome for the 1st time... what's a good firewall gui?
<14> hi there
<9> iptables -L | grep smtp
<9> what's gnome?
<9> Oh,
<9> firewall gui? clueless
<9> I have no earthly idea
<13> lol
<13> ok
<9> iptables -L | grep smtp
<9> ?
<13> tried that... didn't do anything
<9> k
<9> what type of system are you using?
<13> debian
<9> sorry clueless again.
<13> what are you running?
<9> centos, you need to add a line something like iptables -a input -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT to whatever your iptables script is.
<9> or check your script and see if the line for smtp is already configured and commented out or something.
<9> for that matter, you can probably just run that as a command as root
<9> # iptables -a input -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
<15> -A INPUT
<9> what rob0 said
<13> ok, i'll try that... i'm trying to run shorewall to check my firewall that way
<9> well, when you get it sorted out, come back and hollar if you have something else.
<13> thanks cpm
<13> ...and rob0
<16> BoldStrike: It's not gui, but I luv shorewall
<13> hparker: yeah, i just found that out
<13> what's a good gui?
<13> shorewall does look good though
<16> Never used a gui, most of my servers run headless and I admin via ssh
<16> It is, and the docs are nice
<13> very clean
<15> I don't think a good GUI interface is possible if you don't have a firm understanding of netfilter and how it works. That said, I think the Webmin module isn't bad.
<17> hparker: I wish there was a good textstyle gui with window-support of multiple software ;)
<16> wedge: That was linux-conf
<17> ;P
<9> I think what is needed is a good text ui with multiple software style windows
<17> That's what I meant.
<17> anyone know what thepiratebay is? :)
<9> heh
<17> ;P
<17> going drinking with those people tonight.
<15> I have a great text-mode GUI: mc(1) :)
<16> rob0: That's how I learned linux ;)
<15> it's still my primary editor.
<16> As for editor, I'm learning vi as it's on every *nix system out there and I sometimes get to work on Slowlaris and such.. I say learning.. I've been using it 4-5 years at least ;)
<18> Anyone know of a postfix+mysql+dovecot howto?
<19> Petaris: curious, how many users are you going to support with dovecot?
