I'm certainly a big believer in have-to-be-subscribed-to-post, but I sure
can't see what difference it makes whether you look at the envelope sender
or the From: address -- except that if you are using sendmail it is very
easy to set the From: address, and fairly hard to set the envelope sender,
with J. Random MUA.

How does paying attention to the envelope sender help to prevent spam?
