What kind of problems?  It should just bounce the mail with the error "MX
points to myself".

Get rid of the "localhost" top-level zone in your DNS server, and just use
the name "localhost" in your local domain.  That should be sufficient for
people who type "localhost", since their resolvers are usually configured
to append the local domain by default, or they have a hosts file with a
"localhost" entry.
