forward all mail from one sender to one recipient despite the original mail specified another recipient

Question:

Would it be possible to forward all mail from one sender to one recipient despite the original mail specified another recipient?

Answer:

The FILTER: feature in the experimental snapshots can do this with some work.

In main.cf:

smtpd_sender_restrictions =
   check_sender_access hash:/etc/postfix/check_from

check_from contains:

suspect@example.org     FILTER:redirect

In master.cf you define the redirect transport:

redirect ... pipe ... argv=investigate.pl ${sender} ${recipient}

Then do the right thing in the investigate.pl script. See FILTER_README for hints.

The official release of Postfix cannot do this selectively (based on sender).
