There is absolutely no guarantee that the server on the inbound (MX) record also handles outbound and/or IMAP. In many cases, these will be different systems.

It's been at least a decade since I saw a configuration in which the SMTP/IMAP servers were on a different domain than the MX domain. NB: I am not saying that if the MX is mail.example.net "mail.example.net" should be filled in, but that "example.net" should be pre-populated with the opportunity to add, say "IMAP." To the beginning. -- 'Charity ain't giving people what you wants to give, it's giving people what they need to get.'

(Says the man who has to seriously beat even current versions of *Thunderbird* into accepting a manually-entered config and act as a test tool against the IMAPS servers we purpose-built and run for the appliances in the field. "How dare you NOT have an SMTP-out server for this account at all!" etc..)

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