I'm working with Exchange 2007 on a SBS server and have the SMTP receive connector in Exchange setup for port 26. This is to allow Trend Interscan Virus Wall to handle all in bound SMTP traffic from the Internet as a relay. It accepts Internet mail on port 25, then forwards it to Exchange on port 26.
My problem is the POP3 connector in Exchange, which I'm trying to use to download some external POP3 mailboxes. These will eventually disappear, but for now I need to be able to get the mail from these and get email normally through SMTP as well.
The problem is that with the receive SMTP port in Exchange set for 26, the POP3 connector doesn't work and I can't figure out how to change the SMTP port it uses for forwarding the mail through to Exchange.
Anyone know if that port can be changed? If so, how? If it cannot be changed, then I will resort to something like Popcon.
