The problem appears to be specifically with IMAP, so why force every other method of sysop notification (e.g. POP3 email) to include a redundant message body? That's not necessary.

Yes, the imap service could insert a body where no body exists: an empty string, blank line(s), a copy of the subject. Whatever you think is best and appears to work. Less is more.
