This isn't load balancing.  server2 is a backup server, which will only be
used when connections to server1 fail.  As long as server1 is up and the
SMTP server is accepting connections, server2 will never be used.

You need to put an alias on server1 that says that mail for
user2 at domain.com should be forwarded to user2 at server2.domain.com, and
server2 should be configured to forward mail for user1 at domain.com should be
forwarded to user1 at server1.domain.com.
