private message filtering

[Chadi]

Can someone provide some form of hack that allows the admin to insert keywords in a filter, then the vb system will send the admin an instant notification of the private message sent triggered with filtered keywords? Also, that the particular pm is put in some moderation queue instead of being sent immediately.

This would be great. This is for solicititation prevention, spam prevention and moderating any suspicious activity. My forum rules states that pm's may be read for security and moderation purposes.
