SIMS 1.7 CommuniGate 3.2.1 - can't check mail from outside LAN Hi all,

This is my first post to this list.  Happy to supply as much information as possible to resolve this problem as soon as possible.
This mail server has been running for years without any problems.  Will be upgraded soon but in the meantime I have a need to allow users to check their mail from home.  For some reason I always get “invalid user name or password” although I know the username and password are correct.  Can check mail while on LAN without a hitch

Here’s some telnet info which may be helpful:

O-G4:~ orgo$ telnet 25
Connected to
Escape character is '^]'.
220 ESMTP server ready Fri, 4 Nov 2005 01:05:19 +0000
250 Sender <> Ok
250 Recipient <> Ok
354 Ok Send data ending with <CRLF>.<CRLF>
This is a test
250 Message received:
221 ESMTP server closing connection
Connection closed by foreign host.
O-G4:~ orgo$

When I try to Telnet to port 110 and authenticate I get this:

O-G4:~ orgo$ telnet 110
Connected to
Escape character is '^]'.
+OK POP3 server ready.
USER orgo
+OK please send PASS command
PASS ******
-ERR invalid user name or password.

Tried checking mail with Entourage 2004 11.1.0 and Mail 2.0.5 from Mac OS X Tiger 10.4.3.  Same result.
I’ll check the logs as soon as I get a chance to see if there are some clues there.
Running Netgear FVS-318 router if that’s relevant.

Any help would be greatly appreciated.
