I realize this is not your point, but as this is a relatively technical
mailing list a distinction is important: The "From:" field is not the
envelope sender, and we have no indication here that the envelope sender
was altered to match the "From:".
There is no reference whatsoever to the RFC822 From header.
Everything about the original message indicated that the broken
system in question used the user-provided address as the envelope
sender, as that is the only way any nominally correct mail system
would be checking SPF records against that value or sending DSN's to
it.
