I think you will find it is not.  It is the lack of a standards track RFC
reference to it that allows MS to ignore it.  (Just checked - it is 
definitely not in RFC822.)

I'm perfectly well aware of this; I ditch a lot of spam before it even
reaches the SMTP BODY command because the envelope sender domain is
forged.  That you should not auto-reply to header addresses in email
relates to well formed mail.  You should not auto-reply to spam at all,
although you can't help responding to valid headers if you bounce it 
during the SMTP MAIL or RCPT commands, except that some old sendmails
will suppress bounces for some precedences.

I used to regularly manually trace on these and complain to ISPs, but
a lot of spammers these days have rogue ISPs connected via laisser faire
backbone ISPs.
