Re: local_recipient_maps set up, yet postfix continues to send bounce messages
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.
Re: local_recipient_maps set up, yet postfix continues to send bounce messages
Eureka! I have changed the following in main.cf: virtual_mailbox_domains = hash:/etc/postfix/mydomains SHOULD BE virtual_alias_domains = hash:/etc/postfix/mydomains Many thanks to Noel Jones for pointing out that postfix thought we were a virtual mailbox domain, and to everyone who chimed in on this issue.

The example log entry you showed earlier of an invalid address bouncing showed postfix trying to deliver the message with the virtual delivery agent. This happens when postfix thinks the domain is a virtual mailbox domain. - Make sure each domain is listed in only one address class - Use the documented method for listing valid recipients in each address class. This does not include local_recipient_maps = $virtual_alias_maps. - Remove any domain1 - domain2 rewrites. -- Noel Jones
