Maps in $relay_recipient_maps are evaluated as lists - only the LHS is examined to determine if a recipient is listed and therefore a valid recipient.
Does the same apply for local_recipient_maps, virtual_alias_maps and virtual_mailbox_maps when Postfix tries to determine if a given recipient is a valid recipient? I'm asking because I am trying to figure out what I need to do to accept messages for local/virtual mumble domains and have them sent off to a LMTP server afterwards. Sending them off to a LMTP server is a transport map job: recipi...@example.com lmtp:localhost But what do I do to tell Postfix recipi...@example.com is a valid recipient? Can I reuse my transport map and add it to local_recipient_maps, virtual_alias_maps or virtual_mailbox_maps as required? p...@rick -- The Book of Postfix <http://www.postfix-book.com> saslfinger (debugging SMTP AUTH): <http://postfix.state-of-mind.de/patrick.koetter/saslfinger/>
