This is the wrong solution. With this setting, postfix will accept mail to any user address, and you will eventually have a queue full of undeliverable bounces, plus get listed as a backscatter source. The correct solution is to give postfix a list of all valid users. The easiest way to do that is have all users be system users. — Noel Jones _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
