Make sure that GFI is not doing POP proxy. Also make sure that authentication is being used from the client. Remember, Exchange 2000 is locked down for relay by default to only allow authenticated users. This must be passed from the client to the server. In Outlook and Outlook Express there is a check box for “My Server Requires Authentication”. This must be selected or mail will not flow.

If a telnet from the client to the Exchange server answers with the proxy of the firewall, this must be turned off and use filtered SMTP. See KB320027 that I wrote on firewalls and SMTP proxy. This article applies to pretty much any SMTP proxy, not just the Cisco PIX.

Another thing. You need to check your users in AD to verify that POP3 or IMAP protocol has not been disabled for the user.
Also you need to open the relvant ports in your firewall or set up a forwarding rule. POP3 is TCP 110, IMAP TCP 143.
If you use POP3 you get access to the Inbox only. If you use IMAP then you get access to all the folders for the users mailbox.
Think about using secure POP3 or secure IMAP. You’ll need a certificate

Why use pop3 rather than imap. Actually why use pop3 rather than OWA. If you must then the only thing you need do is start the service and punch holes through your firewall.
