Well I removed hostname.domainname.tld from mydestination in /etc/postfix/main.cf and restarted Postfix. No dice...see below:

There should be aliases for each list that look like > LISTNAME: "|/var/lib/mailman/mail/mailman post LISTNAME" > LISTNAME-admin: "|/var/lib/mailman/mail/mailman admin LISTNAME" > LISTNAME-bounces: "|/var/lib/mailman/mail/mailman bounces LISTNAME" > LISTNAME-confirm: "|/var/lib/mailman/mail/mailman confirm LISTNAME" > LISTNAME-join: "|/var/lib/mailman/mail/mailman join LISTNAME" > LISTNAME-leave: "|/var/lib/mailman/mail/mailman leave LISTNAME" > LISTNAME-owner: "|/var/lib/mailman/mail/mailman owner LISTNAME" > LISTNAME-request: "|/var/lib/mailman/mail/mailman request LISTNAME" > LISTNAME-subscribe: "|/var/lib/mailman/mail/mailman subscribe LISTNAME" > LISTNAME-unsubscribe: "|/var/lib/mailman/mail/mailman unsubscribe LISTNAME" I'm only guessing here, but it looks like you have the correct aliases, but somehow they are being processed by a Postfix delivery agent that doesn't understand delivery via pipe to command. What are your actual mail.log entries corresponding to these bounces? This is really a Postfix issue (assuming the Mailman aliases are correct), but to be of further help, we'd need to see the actual Postfix mail.log entry for the bounce and the output of 'postconf -n' to start. Note: you say multiple email lists. If that means some but not all, it probably is an issue with the aliases themselves. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
