Another tool could be to add selective Blacklist queries just for null <> and Postmaster senders and then check these against a backscatter blacklist.

I think this could go a long way to help deter backscatter.Any thoughts on this? If not Message-ID based, is there something else that would be appropriate? I believe Ironport is doing something similar with their hardware devices.TIA for comments...-------------------------------------------------------------------------Check out the new SourceForge.net Marketplace.
