Last week I worked on a mail problem with a Macintosh-based mailer.  
When it tried to send mail to 


and it did not find an MX record for the full name, it did NOT look for
an "A" record; it then looked for an MX record for the sub-domain


and in our case, that MX record pointed to a different mail host than
the "aaa" node, where the recipient's mailbox resides.  Once I added
an MX record for aaa that pointed to itself, mail from this Mac mailer
was deliverable.
