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!
