I am currently running both front end and back end servers behind a
firewall. No DMZ. smtp is enabled on both servers but only accepting mail on
the back end.
The only thing open on the fron end is http and https (OWA)
backend I have mapi, imap and smtp opened.
Question is would it be better to move smtp and imap to the front end
This is a test enviroment. Users will need to do imap, smtp but I am not
sure whats better, put imap and smtp on the front end or backend.
