sender_canonical_maps should take care of this.
In /etc/postfix/main.cf:
sender_canonical_maps = pcre:/etc/postfix/sender_canonical
sender_canonical_classes = envelope_sender
Note: no whitespace before those lines.
In /etc/postfix/sender_canonical:
if /[[:<:]]example\.com$/
/./ [email protected]
endif
Note: no whitespace before those lines.
That will replace a MAIL FROM sender not in your domain by your
own address.
