Let Acme mail pass "From:" headers through to the
message that gets sent to upas/marshal. I wasn't
clear at all on what the motivation was for treating
it as an additional "To:" line, but if that's
desirable, just replicate the TO case for FROM with
delit set to 0 instead of 1.

Notes:

    The reason that acme treats From: as To: is so that
    if you are reading a message you can actually
    just edit the body and click Post to send a reply.
	that's why it's not correct to send the entire From: line.
	it's usually someone else's info!
