:I'd discourage them (sigh) unless you're willing to send out a lot of
:mail on their behalf to people (like me right now, sigh) who have

:no ridiculously popular service or person there, so chances are this
:at->@ bug is still in a good many sendmail.cf's.

I have also noticed problems with hosts (or subdomains) the same as
the two letter national codes.  Some sendmail.cf files look for these
and assume the terminal part is just added junk and strip it.  Not
right but it evidently is out there.
