How can I set up Exchange 2000 Server to pull mail from a POP3 account?
Small Business Server (SBS) 2000, which includes Exchange 2000, has a built-in connector to pull POP3 mail, but Exchange 2000 doesn't. POP3 redirection is fraught with potential problems, including the strong possibility that you'll end up creating a mail loop, either on your server or someone else's. You're better off investigating and using extended turn (ETRN) or TURN to let the remote server accept your mail and then dequeue it to your local Exchange 2000 server on demand; this approach is fully compliant with the Internet Engineering Task Force (IETF) Requests for Comments (RFCs) for mail addressing, routing, and delivery, and it works well with Exchange Server 5.5 and later. See http://www.swinc.com/resource/exch_dq.htm for information about how dequeuing works and how to use it. If you insist on using a third-party POP3 connector for Exchange 2000, you might consider DataEnter's POPBeamer for Microsoft Exchange; this program is reported to cause relatively few problems for this class of product.
