See virtual_mailbox_maps, virtual_mailbox_domains etc
When I designed a similar system I delivered email using maildir format boxes
over NFS, so all the front end servers "thought" the recipient was local to
them (as a virtual mailboxes) when in fact weird NFS mappings were hidden at
the filesystem level. Afraid I never got to see how well it scaled outside
You could equally define maps for relaying that deliver user1 to server1 using
SMTP instead of NFS, but that seems unnecessarily involved to me.
