This is a common speculation, but does anyone know of an actual mailer like
this?  The only thing I can think of is the version of sendmail on SunOS
4.1.x; those systems came with sendmail and sendmail.mx, and you were
supposed to replace sendmail with sendmail.mx if you're sending to the
Internet.  By now I would expect most administrators of such systems to
have noticed the problem and done so (we used to get lots of calls from
customers with this problem, but I don't think we've gotten one in at least
3 years).
