It should also include a "Sender" header of "[EMAIL PROTECTED]", by the
RFC, indicating the mailbox that sent the email on the behalf of the
indicated sender.

Further, the issue is that the recipient cannot meaningfully respond to
the *sender* of the messages, only to some other address.  The sender,
attached to the envelope, is "apache@", and has nothing significant to
do with the content of the From header in the body.


It is perfectly legitimate for the recipient to act on the SMTP envelope
details, and RFC mandated that your scenario permits them to do so by
way of the Sender header...[1]

*shrug*  So, send it from an appropriate email address.

Return-Path, Sender, and the SMTP envelope.  You should fix *all* of
those to be deliverable for responses.
