Well, I do not understand it now.

domain.tld has:
mx 20 some_server2
mx 10 some_server1

If we are talking about postfix configuration on backup server -
some_server1, it has to forward messages to some_server1, so
postmap -q domain.tld mysql:/etc/postfix/sql/transport must return
smtp:some_server1 or smtp:[some_server1_ip_address].
