On our current install (7516) web mail searches for full email addresses always return no results. I didn't see this being something that was fixed in the releases after 7516 so I am curious if this is a bug or something wrong with our install.

- search for domain.com will show all emails from the domain

- search for user@domain.com has no results

- search for just 'user' works, so the @ appears to be breaking the search

- tested on multiple accounts for multiple domains

- reloaded domains, and re-indexed users, no change
