What is this?
An External Agent for ORF that improves ORF with backscatter detection (requires ORF 2.1 or newer).
What is backscatter?
Backscatter (or "reverse NDR") attacks occur when a spammer sends large amounts of email in the name of your domain and your email server gets bombed by bounce reports (also called DSNs or NDRs) from legitimate servers.
