Recipient Filtering not working in Exchange 2007

Posted on 2011-10-17
Last Modified: 2012-05-12
I have enabled the Exchange Recipient Filtering and added an address, sent an email from the email that was setup in the Recipient Filter to be blocked and the mail is still getting to end user. I have verified the configuration from the Exchange Shell and all information looks good.  Help with this would be very much appreciated.


Info from exchange:

    Did you install Exchange anti-spam agents ?

    Did you restart Exchange Transport service after that ?

    I am sure the Anti-spam agents are installed because in the GUI i see the Antispam tab and i have entered in the email address i need to block. I just simply want to block a single email address from sending to our users.

    ok i got the filter working i was editing the wrong group in the gui. But is there a way for exchange to just delete the message and have the user sending the message think it was sent correctly. Right now when i send with my test account i get a NDR telling me sender denied. I would not like for the user i am blocking to know that we are blocking there email address.

    But is there a way for exchange to just delete the message and have the user sending the message think it was sent correctly.
    >> Yes
    Exchange Transport Rules
    See the screenshot guide here

    In the actions tab, you would want to select - Drop Message Silently.
