I have recently installed Windows 2003 Server SBS with Excahneg 2003. The company that is currently using hosted POP3 accounts at their ISP. I have tried without success to setup the POP3 connector for them but everytime I send a test email through it gets to me, and then I reply, but they never recieve a response. At first I didn't have the POP3 connector service setup to start automanticly, but I have since corrected that. I'm sure the server, username, and password are correct as they can get the email from a web based interface. Anyone have any suggestions?
