Win2003Server\Exchange 2003 ....Am I under a reverse NDR Attack ? ... I Enabled Recipient Filtering with Tar Pitting on Exchange. Our DSN queue is huge and internal emails have a delay of up to 2 hours before being delivered...I deleted over 500K emails sent to postmaster@mydomain.com the past few days and configured exchange not to send anymore NDR's however my server's Event Log is still receiving "Error 3017 & a NDR with status codes" stating that spam@mydomain.com is being rejected from another server in my domain.

Any Help is Appreciated !
