It is very well documented that mail *REQUIRES* working DNS; much like
Kerberos.  No DNS then no mail, no authentication, ....  This should be
considered a hard requirement;  the solution is to fix your name
resolution.  Either use a valid FQDN or make the FQDN valid.

The simplest [and it is very simple] solution is to run a bind instance
and configure the server to use that for DNS.  Bind is simple to
configure and local DNS has a million and one advantages.

If you have an 'internal' domain that domain should be resolvable
internally.

Fixing DNS to work in an expected normal manner is much simpler than
hacking your way around having broken DNS.
