That sounds like something similar to what happened to us when someone decided they'd reconfigure our mail server to send from a different ip address than we receive mail on. We got away with it for a long time, but as more recipients installed spam filters (this was a few years ago), we began to see more bounces when we sent mail. Fixed by setting up reverse lookup for the sending address.
