Have a look at the link I included.. the 4.4.7 is coming from the receiving server at the destination domain, because it's having problems looking up the MX record.. (I think).

Does it have both servers listed as bridgeheads? Try having just CityB listed. This means that when ServerA sends a mail it will travel to ServerB, and ServerB will send it on.

They see each other just fine, I can move mailboxes, etc. City B can send to the internet just fine, but an email to a City A mailbox gets a 4.4.7.
