I agree that we are being hit by a spam/ndr attack.
However we have turned off NDR's on the server. We also
get the Netskyp virus on our server alot, against my best
efforts to keep the AV software up to date. So any
thoughts on why NDR's are still being sent and how we can
prevent the Netsky virus.

Thanks
Chad
