FYI, Exchange2k, 2k3 CAN block unknown users at the SMTP level, but it does NOT come configured to do this by default. If the company you are spooling mail thru your IMGate for doesn't have this configured correctly, consult with them to configure this properly, then you can use RAV and it will work as advertised.
http://support.microsoft.com/default.aspx?scid=kb;en-us;823866#6 Apply a recipient filter, the important setting here is "Filter recipients who are not in the directory". Once this filter is defined and applied to the SMTP server, users who are not in AD (i.e. unknown mail recips) will get blocked during the SMTP connection, and your RAV filter will get good data. Some docs I read say that MS doesn't set this by default because they feel it makes the Exchange server vulnerable to dictionary attacks attempting to find valid email users/logins.
