I have configured some domains as a virtual domains on a Linux system running Postfix. For each of these virtual domains, only a few users happen to be on this system and the rest of the user mailboxes for these domains are on respective external hosts. In order to deliver the mails being sent by the users on this system to the users of virtual domains on external hosts, I tried using fallback_transport_maps for the virtual domains but it does not seem to work and all such mails are bounced back.
Where can I specify fallback transport for each of these virtual domains? Thanks, -- Manish Kathuria
