whoops! uncloaked. i am just another bozo on this bus.

the hostname pissing contest is way old. i fall on the liberal side.
e.g. in this case, some poor end user stuck an underscore in their
config. i just can't expect them to be well-versed in hostname arcana.
to the best of my memory, that HELO check was just to catch when there
is no fqdn.

and, for your daily pedantic amusement, in pure dns, foo.bar.com might
reall be "foo.bar," a single lhs name, in the com domain. dns is 8-bit
clean, with segments having lenth, not being dot delimited. so dots can
be in name segments.
