I am running exchange2k on a sbs2k. Does anyone know if I have to shutdown the ndr in order stop receiving so much spam? If yes? is there a consequences where something wont work? I am recieving tons of spam into my madmail folder. I have deleted but it comes back a lot more.
 
By disabling NDR's to the Internet, you effectively thwart spammers that probe your mail server. If they recieve an NDR from your server, then they know your server exists and will begin flooding it with spam in hopes of hitting an existing mailbox.

From a business perspective, disabling NDR's to the Internet means that if a customer sends an email and accidentally misspells it, they'll never know it wasn't received.

You can disable NDR's to the Internet and it won't effect anything else.

Stopping NDR's will not stop spammer that have your addresses, but reduce more spam in the future.
There are no real consequences, except, if a customer sends to a wrong address, he/she will never know.

A way to intercept that is to forward NDR's to a seperate account for you to check regularly.
