The ability +to get in contact with a person responsible for IP address routing or machines +involved in an ongoing attack in a timely manner is critical for internet +stability and operational security. + +Sadly, some junior administrators have decided that standard internet +background noise constitutes critical abuse behavior and automates sending +abuse emails in response. This floods abuse inboxes and makes the global abuse +reporting system less real time and, thus, less able to respond to actual +attacks. + +Worse, these automated abuse senders rarely respond to follow-up or requests +for more information, making it clear they don't actually care about the +"abuse", they just want to send spam. + +To combat this, we completely block any automated abuse senders after several +attempts to reach out and resolve the issue if we receive no response. Further, +we block all messages coming from common auto-mailers. The two files in this +directory are regex lists compatible with postfix's `header_checks` and +`body_checks` configuration options, and should block most spammers who hit +abuse inboxes. diff --git a/body_checks b/body_checks new file mode 100644 index 0000000..3ce5043 --- /dev/null +++ b/body_checks @@ -0,0 +1,2 @@ +/^\[this is aDs \(AutoDefenseSystem\), please report any abuse or illegal redistribution of this software to the author Mr. Davide Lemma.*/ REJECT AutoDefenseSystem delivers abuse reports to non-abuse contacts.
