DONEDirectory Harvest Attack (DHA) Protection

| Last activity: 9 years ago
Add a new test to ORF that would temporarily reject all delivery attempts if the sending IP address is sending to more than "X" (user-configurable) non-existent recipients within in a specified period of time. This would provide some protection against poorly distributed or non-distributed Directory Harvest Attacks.
