... and contravenes RFC 2822, as I read it:
In all cases, the "From:" field SHOULD NOT contain any mailbox that
does not belong to the author(s) of the message. See also section
3.6.3 for more information on forming the destination addresses for a
reply.
(1) However, it's only a SHOULD NOT, not a MUST NOT.
(2) I suppose one could get into deep philosophical arguments about the
concept of "belonging" for a non-existent mailbox. :-)
From: and Date: are now the only two required header lines in a message.
I think the idea is that From: should give some valid information about
the origin of the message.
