    My server has 2 ports one behind a firewall and another on the local network, my pop3 on the local network works the one behind the firewall doesn't. The firewall has the proper ports opened, is there a simple way to check the packets get to the server ?

    netstat -tap
    will show on which IP addresses programs are listening. you should see either or *
    $ netstat -tap | grep pop
    (Not all processes could be identified, non-owned process info
     will not be shown, you would have to be root to see it all.)
    tcp        0      0 hosted.by.obfuscated:pop3s *:*                         LISTEN      -                   
    tcp        0      0 *:pop3                      *:*                         LISTEN      -

    the most simple way to do this is actually use telnet domain 110, then use the command user <username>
    then pass <password>
    you should get authenticated if all works wel,

    anyhow the firewall config was wrong a typo in the forwarding rule, this procudure was really helpfull,
