Actually, the Return-Path is what is called the "envelope from".  The From
you see in your mail client is strictly cosmetic and anything can be put
there.  Also look at the last received line of the server connecting to you.
The access database will also look there.  There are some ways to limit the
access database to only look at the Return-Path or the received line.  Check
the sendmail documentation for those.

I am not sure about the RFC reference.
