POP3/SMTP-IPTABLES Problems


Hi guys... I'm getting pretty frustrated with IPTABLES.... I can't figure out how to properly set the rules so that I'm able to send and receive emails from behind the firewall. Actually... I don't even know what the actual problem is really but I'm sure it has to do with either IPtables, dns, mx records maybe or all of the above. All I know is that sendmail is sending fine from the server and pop3 seems to be fine as well as I can telnet to it, although when I use sendmail to send a message to root@mydomain... I don't seem to have messages waiting when I telnet to pop3 afterwards... I have no idea what else to do...

any help would be greatly appreciated!

cheers! )

Have a look in the sendmail log files to see what it has done with the message.
If you can send to sendmail ok, it will place some info about what it has done with the message.

/var/log/maillog
