A user can use any From: header they like, but it will (by default - see
my posting about trusted users) insist on an authenticated Sender:
header and envelope sender. This is what you want on a multi-user system
with untrustworthy users. It was the "standard" way of doing things 10
years ago when personal computers on the net were unheard of. Times have
changed, and I guess people have to accept these days that there are
just going to be more forged sender addresses.
