The exact same way that filtering mail from MAILER-DAEMON@anywhere prevents loops. Set up a list TEST-L. Subscribe a broken address to it, that will get a bounce from [log in to unmask] Post to the list. Catch the bounce message because MAILER-DAEMON is filtered. Now add 'Filter = Allow,[log in to unmask] Now post to the list. Now dive for cover, and be ready to inject a 'HOLD TEST-L' command when you're tired of watching the looping. ;) There's some mail systems that use 'administrator@' instead of [log in to unmask] That's why that address is in the default filter list. -- Valdis Kletnieks Operating Systems Analyst Virginia Tech
