Mail::Milter::Module::HeloUnqualified - milter to check for an unqualified HELO name

       Todd Vierling, <tv@duh.org> <tv@pobox.com>

       This milter module rejects any domain name that HELOs without a dot, and which is not an IPv4/IPv6
       literal.  Whether or not the HELO value corresponds to the connecting host is not checked by this module.

       If the EXCEPT argument is supplied, it should be a regex enclosed in a string which will be exempted from
       this check.  Commonly, '^localhost' is excepted.
