Last month I suffered a Reverse NDR attack on my Exchange server, even though I had recipient filtering configured correctly and turned on, on the default SMTP protocol.

I've since configured the Exchange server to do "tarpitting" , but is there any insight into why the recipient filtering didn't work on it's own accord ??

thanks,
