Inbound Mail Swallowed

jfb3 · Apprentice Joined: 01 Feb 2003 Posts: 242

I've (tried to) set up Postfix, courier-pop3 on my server. I can send outbound through it. Inbound mail doesn't bounce back to the sender but I can't seem to find it either. I can authenticate (I use kmail on my workstation) but no mail. When I poke around and look in some likely directories on the server I can't seem to find any messages.

Does anyone have any ideas?

Here are (I think all of) the relevant portions of configuration files:

Let's start with some basic testing.

1. Is the server up and running? A simple ps -ef should tell us that.

2. What IP address is it connected to? netstat -ptln should show 0 0.0.0.0:25 and the postfix pid

3. Does it deliver mail when you connect directly to it?

1. Yep
2. tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 1332/master
3.-4. When I telnet (using ktelnet) from the server (or any other machine from beind my firewall) nothing ever says "ok".

ktelnet localhost 25
Trying 127.0.0.1...
Connected to localhost (127.0.0.1).
Escape character is '^]'.
mail from: me@ispdmain.com

...no response...after a minute I killed the connection...

[On a good note ports 110 and 143 seem to answer correctly.]

There where no messages in the Maildir/new directory that's what worried me the most.

5. The response to dig appears to give back good info (I guess):

That's really odd. I'm thinking that something might be wrong with Postfix itself. At this point remerging it might be the best idea. Do the logs say anything interesting? Actually looking at the logs while you restart Postfix might be a good idea as well. Here's one from my server now that I've got some time to do this properly.

Should of have you pull the logs to begin with.

/etc/init.d/postfix stop
vi /etc/mail/aliases
/usr/bin/newaliases
/etc/init.d/postfix start

That should take care of the problem.

There was never any mention (that I remember) in the postfix documentation of needing to issue that command. It all works now.

Thanks again.

There's a message about it after the emerge finishes. You probably missed it if you installed several things at once. No worries.

I've got the same problem. Outgoing mail is OK. Authenticating is OK. Incoming mail arrives to the spool (/var/spool/postfix/deferred) directory under referred, but never makes it to the maildirs, so neither pop, imap or mutt get any mail.

btw: using postfix with courier-imap for pop3 and imap
