It is very very common. 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."
