The first question is has it ever worked, if yes, then what changed since it
last worked, either on your network on the account, confirm with your ISP
that the Zone file us still properly set up and that it has not changed.
You should be able to telnet to the pop3 account on both ports (25 and 110)
if not, it could be a firewall problem (More than likely) if you are behind
a firewall or router configuration i e access list et all or that the
account is incorrectly set-up or non assistance. If I were you I'll be
getting unto my ISP, they need (amongst other things) be able to telnet to
the pop3 account on port 110.

Use the "log" keyword on your access lists if your IOS version supports
it (I think 11.x) so you can see which lines deny or permit which
packets on which interface, If you don't or can't, you can also use
"show ip accounting access-violations".
