Configure the appropriate bounce-recipient and use a transport map
to pipe mail for that recipient into a script:
/etc/postfix/main.cf
notify_classes = bounce, ....
bounce_notice_recipient = u...@example.com
transport_maps = hash:/etc/postfix/transport
/etc/postfix/transport:
u...@example.com bounce-pipe:
/etc/postfix/master.cf
bounce-pipe .... pipe
flags=xxx user=yyy argv=/path/to/script
# postmap /etc/postfix/transport
# postfix reload
The bounce message contains the failed recipient (the Final-Recipient:
field) and the envelope sender (the X-Postfix-Sender: field). An
example of all this is at the end of ADDRESS_REWRITING_README.
