Subject: How can I force all users to use encryption ?

What options must I change on the CommuniGate Pro administration interface to force all users to use encryption, on all protocols (POP, IMAP, SMTP, LDAP, HTTP, etc..) ?

I can't just disable ports 110 (POP) and 143 (IMAP), since I want STARTTLS on those ports.

I can't also disable port 25, since it's used for receiving email from external domains, and some of them may not support encryption. I want to be able to receive unencrypted email from those external domains, must I want to force internal users to use STARTTLS on port 25.

I want to make sure there's absolutely no way the user's passwords can't be captured.
