If there is, _that_ is a bad idea. There are other things that
can be broken by indiscriminate RFC2821MailFrom rewriting.
I morally, ethically, uncategorically hate, despise any protocol that
tampers with mail, including and especially network control lines or
headers. It just invite even more tampering, kludges, complexity and
potential foul ups.
