    I currently have ISPConfig running on a Debian 8 Server using ISPConfig 3.1 and I am having issues with sending mail outside of my mail server or receiving mail from outside addresses.

    Here are my results from the common problems script in the Sticky:
    Code:

    When I email inside the local server-either to other domains or just sending test messages to myself-the emails are sent and received fine. However if i try to send or receive mail to/from outside my server it never arrives. For sending I have checked the mail logs and no matter what mail provider I attempt to send to I get connection timed out for IPv4 addresses and network unreachable for IPv6 addresses:

    Attempting to perform a basic telnet test produces the same results, I get connection timeouts to any receiving mail server I try.
