You might make sure neither of the servers thinks it should respond for the
IP of the other. Maybe when you migrated the sites, the IP of one site was
still set at the old servers IP. So, look down the site list and check the
IPs.
And that the site you are trying to send email to , does not exist on the
old server at least as far as mail server aliases.
Or your DNS is not updated yet.
