The NDRs are really no different than any message in that your server will
retry delivery of them for X days before failing. You can choose not to send
NDRs at all, but that will affect legit business mail, too - and you
probably want your company's valid senders to get an NDR if they misadress
something, rather than thinking the message got through....

If you're getting a ton of spam and don't want to send NDRs to every scumbag
spammer who tries to send mail to your domain, it may be time to invest in
anti-spam software or services....see www.gfi.com for one or www.postini.com
for the other.
