> Make sure you understand address classes. We are not a virtual mailbox domain, we are a virtual alias domain because we use UNIX accounts for the few mailboxes we have, and alias several other addresses to them. Here is the definition of a virtual alias domain straight from the manual:
The virtual alias domain class. Purpose: hosted domains where each recipient address is aliased to a local UNIX system account or to a remote address. A virtual alias example is given in the VIRTUAL_README file. Domain names are listed in virtual_alias_domains. The default value is $virtual_alias_maps for Postfix 1.1 compatibility. Valid recipient addresses are listed with the virtual_alias_maps parameter. The Postfix SMTP server rejects invalid recipients with "User unknown in virtual alias table". The default value is $virtual_maps for Postfix 1.1 compatibility. There is no mail delivery transport parameter. Every address must be aliased to some other address. >Apparently this is a virtual mailbox domain. Valid users must be listed in >virtual_mailbox_maps. Domain rewrite wildcards will break recipient validation. Again, it is not a virtual mailbox domain, and there are no wildcards used anywhere I am aware of. >I don't see anywhere that document recommends setting local_recipient_maps = >$virtual_alias_maps. That looks like a hack someone dreamed up for covering >broken address classes. Because we are a virtual alias domain, this is where our users are all listed.
