You're using Small Business Server 2003 then? Have you worked through this article? How to troubleshoot the POP3 Connector in Windows Small Business Server 2003 http://support.microsoft.com/kb/885685 "It's worthwhile to aggressively investigate alternatives to the POP3 connector. The Internet is strewn with digital carcasses of mail administrators who tried to use POP3 connectors to manage their e-mail services. The POP3 connector should be used as a stopgap measure, for a very limited amount of time during the time you're settings things up to enable the Exchange Server to receive incoming e-mail." - Tom Shinder After you are working with the POP connector, I would follow Tom's advice here and establish SMTP delivery. Can you engage a service like dyndns to allow for STMP delivery?
