I am having issue with my mail server I am relatively new to Exchange here's what I found so far.
Connections from the Internet to the box on port 25 work.  Port 110
incoming is and has always been closed.  To get emails from outside you
will need to use http/https.  From inside, we have no control on your
access to the server, but the server is responding to port 25.      It is
NOT responding to port 110 (POP3), so there is a problem on the server
itself.

Another issue we see in the logs is the following:

Your MX record is not properly and completely set up, so AOL is
rejecting your emails.
