I'm using virtual mailboxes (virtual_mailbox_domains, virtual_mailbox_maps, virtual_alias_maps) and now want to use something like transport_maps so I can control where the mail is relayed to based on the recipient domain. There appears to be no equivalent when you are using virtual mailboxes, like virtual_transport_maps. The documentation says that virtual_transport is only a final destination type of setting so I'm wondering if there is a different way to accomplish this.
