Hello all,
We are getting ready to move our clients from sending smtp on port
25 to sending on a different port to avoid problems with ISPs
blocking outbound port 25 traffic. However, we have a group of test
users who are using MAPI, and we have not been able to find the
setting to change the outbound port. Could anyone offer some
clarification? Does a MAPI connection do everything through port 143?

Yes, with MAPI, messages are send via the CGPro IMAP extension XSUBMIT
command, so everything is port 143 (unless you're using SSL).
