Exchange 2003 SP2. We have a user that needs POP access to manage bouncebacks for an e-mail listserv. When I telnet to port 110 I get this:
+OK Microsoft Exchange Server 2003 POP3 server version 6.5.7638.1 (EXCHANGE01.domain) ready.
-ERR Protocol error.
POP3 is enabled for my user account on the Exchange Features tab of ADUC.
How can I fix this?
