That caused my confusion. I had expected that for local submissions as well. >>> And where did this mail originate?

Only virtual alias domains > have recipient validation done by the queue manager (via > trivial-rewrite). That figures. A "telnet localhost smtp" verifies that. Which makes all recipients (save one) bounce; I need a mailbox map, then. > If local mail is sent to non-existent users, you'll need to configure > dovecot (or other delivery agent) to know which users are valid. > > Alternatively, make the domain a virtual alias domain, and rewrite > all valid users to some other domain actually used for delivery. There should be no local delivery; I'm happy with that. Thanks for pointing out my oversight! After changing my virtual_mailbox_maps virtual_alias_maps = proxy:ldap:/usr/local/etc/postfix/example.com-groups.cf proxy:ldap:/usr/local/etc/postfix/example.com-users.cf virtual_mailbox_maps = $virtual_alias_maps ... things start working out. I'll have to remember to test using "telnet localhost smtp" to verify. Regards, Jeroen. -- Jeroen Scheerder ON2IT B.V.
