IMAP requires a password. SMTP it's optional.
Not at the University of Minnesota. We require ESMTP STARTTLS/AUTH over the standard mail submission port (587).
The question is: How do you enforce it on submission via port 25?
We do allow the same thing over port 25, but only for backward compatibility. (If you try using either port without STARTTLS+AUTH, it will not work.) And of course for those non-standard MUAs (i.e. older Outlook) we also do support port 465 (SSL) and require AUTH there as well.
Sorry, my above question was bad worded - it should have been: The question is: How do you enforce submission via the submission port (and inhibit submission via port 25)?
Postfix can be configured in this manner, although I am not really sure what it gains you.
