When you enter your email address, it would be TRIVIAL to check the MX records for the domain and fill those in for the SMTP and IMAP servers, allowing users to more easily add (if needed) the domain prefix.

My current $WORK used to have different incoming MX servers vs the outgoing, since we used an external spam filtering service.
