Having just spent gods know how much time hacking up sendmail, this is a
problem... here's why..

* Sendmail only does this under SMTP, not under anything else

So, that means that Mailman would have to accept its messages over SMTP,
which sin't in itself a problem... the problem is that as far as I've
been able to determine, sendmail can't be told to deliver SMTP mail to a
different port than 25.  Also, you'd end up with mailer re-write rules
out the ying-yang :-)  Trust me, you never ever ever ever want to do
anything that requires someone to add anything bizarre to their sendmail
installation.

That's not nearly as ugly as the problems with doing it ... also it'd be
different for every mailer, and quite different in many cases I think.
