What's wrong with this DNS entry?

I know someone with a godaddy linux box, that when you try and do a lookup
of the MX record returns this:

dig somedomain.org mx +short

20 213.67.173.4.somedomain.org.



It should just return somedomain.org. What exactly is wrong with this DNS
record?


-Thanks

My guess is the MX record data field in the zone file was wrongly filled
with a IP address while a host name is expected. So the dotted quad form
of the IP address is considered as an unqualified domain name (no
trailing dot) and is appended the current origin, which is zone domain name.

Some idiot put an IP address for the MX target and left off the dot at
the end. Find the person who edited the zone file last and revoke
their privileges until they read "DNS and Bind" and pass an exam on
it.
