Does netstat show your server listening on port 110? For example you could run the following command:

Code:

netstat -na | grep 110

This would show you if the server is even running the POP3 daemon. Another test might be to telnet to port 110, for example:

Code:

[root@server ~]# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
+OK Dovecot ready.
USER <username_here>
+OK
PASS <password_here>
+OK Logged in.
stat
+OK 0 0
list
+OK 0 messages:
.
quit
+OK Logging out.
Connection closed by foreign host.

This would check to see if your POP3 daemon is running correctly.
