Have you checked to see what the privacy settings are? It's possible that certain settings will cause the email not to go to MLS. (MLS has no concept of privacy).
You might also try a unit refresh. It's possible that sync was broken for a time and all changes during that time never made it to MLS. A refresh would fix that.
