Yes, which is why I said "technically". Most often, a difference
between envelope-from and From: header is because of a resending, like
when Mailman sends mail on behalf of someone else; the From is still a
valid address, but it's not the same one as the envelope-from (which
will be the list-bounces address).

That said, though, I've often telnetted to a mail server and done
something like this:

"""
helo
mail from:<some real address>
rcpt to:<another real address>
data
From: me
To: me
Subject: Test

Test!
.
quit
"""

Generally that sort of thing gets through. Sometimes it lands in a
spam box, but more often it doesn't. I don't remember it ever getting
rejected, other than for issues of relaying (which usually come from
typoing the recipient domain).
