Wrong.  Completely wrong.  Any UNIX-like box with qmail can be configured
to send mail out.  My laptop, for example.  But my domains only receive mail
at the servers designated as MX hosts in DNS.

What Paul is *trying* to do is deal with the fact that any Windows-like
box with spamware is *also* configured to send mail out.

What he's *looking* for is called "SPF", not "outbound MX".

(Whether SPF is actually workable is a different subject entirely - however,
it *is* the closest thing we have to a "standard" on how to tag things the
way Paul is wishing MX were done....)
