I think you have to run dovecot on the server receiving mails, just 
don't open imap/pop3 ports so users can't get there.  Then publish the 
other server as your imap/pop3 server.  Both servers probably should 
have the same setup for postfix and dovecot, but just kill the ports on 
the one that doesn't need it.  To run lda you're going to have to run 
dovecot on your mail relay.
