We are looking for suggestions to institute content filtering of user to user emails inside our domain. We have come across words that should be blocked and are not. We have a barracuda spam firewall for in and out of domain filtering so we would need something to work in conjunction with that. We have had prior suggestions like Marshal, Brightmail, GFI or cloud based like FOPE from Microsoft but these products appear overkill. We have also tried Organization Configuration > Hub Transport > Transport Rules > New Transport Rule
Under text patterns all the different words or phrases of words can be added. If forward for moderation is selected a mailbox can be selected and that person can approve or disapprove the message. Gut all emails are being sent to moderator.
We are running exchange 2010 sp3 rollup 7
