    Default [SOLVED] Unable to use POP3

    I am having a heck of a time trying to connect any mail client to our zimbra mail server.

    I've been reading the forums and it seems to be an easy task but I'm not sure why its not working for me. I have opened the port 7110 for pop3 on my firewall. But I can't see it from the outside. I'm not sure if it is a zimbra problem or a firewall issue.

    Thanks for your help,

    If you need any additional info please let me know.

    A couple notes:
    Perdition is enabled. Disable that, otherwise on reboot your server won't start up. You only use perdition (POP3/IMAP Proxy) if you have a multi-server set up, and most people don't.

    You can find the setting in the admin ui.
    Next, let's make sure it's stopped:
    su - zimbra
    zmperditionctl stop

    Finally, pop3 is on port 110. Perdition runs on 7110. So make sure you have port 110 forwarded.

    Thanks for your help, I disabled the imap/pop proxy and even followed the disable perdition options from the wiki. But I still can't connect to pop3 on port 110. Can you please review my configuration? Thanks

    Code:
    zmperditionctl status
    imap4 is not running
    imap4s is not running
    pop3 is not running
    pop3s is not running

    You still need to flip the ports, as you have:
    zimbraPop3BindPort: 7110 (this should be 110)
    zimbraPop3ProxyBindPort: 110 (make it 7110 even though you're not gonna use it-perdition)
    zimbraPop3SSLBindPort: 7995 (this should be 995)
    zimbraPop3SSLProxyBindPort: 995 (again make this 7995 even though your not gonna use it)
    Check your global and server settings in the admin console as they may differ. -If you need CLI syntax let us know.

    I changed the global values as well, restarted zimbra, but I still can't access pop3.

    I tried telneting from the lan (behind the firewall) to the ip of the server conencting to port 110 and nothing comes up.

    I know you said you tried from inside the lan, but externally you only have 22, 25, 80, & 443 open. Are you sure you're not resolving the external IP (and attempting to route out then in) for your tests?
