The "bounce" I got had an envelope sender address of dbmail@xxxxxxxxxxxxxxxxxxxx rather than MAILER-DAEMON@xxxxxxxxxxxxxxxxxxxx (or <>) and hence wouldn't be caught by that rule. I have: From:dbmail@xxxxxxxxxxxxxxxxxxxx ERROR:5.7.1:550 Bounces go to the envelope sender address, not the header sender address And that's certainly working according to /var/log/maillog Paul.
