Exchange 2013 cu10
i can't seem to figure this out. from the CAS server itself, i can telnet to localhost port 110 but from anywhere outside that host, even servers next to it, i am unable to. there is no firewall enabled in my CAS server as well as the other server's i tried
to telnet from. i also used Thunderbird with a POP3 account and it is working. but not telnet to port 110.
is there something i may have overlooked?
