To override the bounce address and the From: header:
/etc/postfix/main.cf:
sender_canonical_maps = static:[email protected]
To override the bounce address without changing the From: header:
/etc/postfix/main.cf:
sender_canonical_maps = static:[email protected]
sender_canonical_classes = envelope_sender
