I most strongly agree!
We have been doing it that way for some months now and it works very well.
The problem is, that in standard sendmail you cannot determine where the
mail came from. There are some sites around here with binary licenses.

After one of the previous debates about that we did "compile" a /bin/rmail
that converts addresses to an unabiguous form giving ! precedence.
That way our sendmail.cf can give @ precedence as we need for Bitnet
and local networks. This means address and header munging two times but
you don't have to change sendmail.

I would be happy to send the stuff to sites who can't/won't change
sendmail.
