http://hg.dovecot.org/dovecot-2.1/rev/f562bcaca215 implements "postmap" type sockets, which follow Postfix's tcp_table(5) protocol. So you can ask:

get user@domain

and Dovecot answers one of:

 - 200 1
 - 500 User not found
 - 400 Internal failure

So you can use this with Postfix:

virtual_mailbox_maps = tcp:127.0.0.1:1234

With Dovecot you can enable it with:

service auth {
  inet_listener postmap {
    listen = 127.0.0.1
    port = 1234
  }
}

Anyone have ideas if this could be improved, or used for some other purposes?
