You name resolution setup is broken. You need to fix it.

The relay is localhost? Ah, because you get the mail via fetchmail.

Yes, you must setup DNS proper. If using bind then check your bind
configuration. If you do not use any own name server then check the
/etc/hosts file, /etc/resolv.conf and /etc/nsswitch.conf to be proper.

You could use FEATURE(`accept_unresolvable_domains')dnl. But only using
that and not fixing your broken DNS setup would be "unwise"
