I don't see anywhere that document recommends setting local_recipient_maps = $virtual_alias_maps. That looks like a hack someone dreamed up for covering broken address classes. Anyway, this won't have any effect for a virtual_mailbox_domain, which is what it appears you're using. > > - what is being bounced? > mail sent to non-existent aliases/users (not in virtual_alias_maps) > > - what address class (local, virtual-alias, virtual-mailbox, ...) is > bouncing? > virtual-alias Make sure you understand address classes. http://www.postfix.org/ADDRESS_CLASS_README.html Each domain postfix is responsible for must be listed in *only one* address class, one of: - local addresses, domain listed in mydestination, valid recipients listed in local_recipient_maps - domains relayed elsewhere for final delivery, domains listed in relay_domains, valid recipients listed in relay_recipient_maps. - virtual alias domains, domain listed in virtual_alias_domains, valid recipients listed in virtual_alias_maps (and must be aliased to another domain). - virtual mailbox, domains listed in virtual_mailbox_domains, valid users listed in virtual_mailbox_maps Usually people break recipient validation by using @domain <> @domain rewriting in virtual_alias_maps or in canonical maps.

Valid users must be listed in virtual_mailbox_maps. Domain rewrite wildcards will break recipient validation. > Oct 14 13:37:37 mail postfix/bounce[21056]: A887A1A084D7: sender > non-delivery notification: B87541A084D9 > Oct 14 13:37:37 mail postfix/qmgr[21037]: A887A1A084D7: removed > > -- Noel Jones
