Abuse Reporting Format
The Abuse Reporting Format (ARF) is intended to standarize, until now with a draft, Feedback Loop emails. These emails are warnings about an ilegal use (in this case, spam sending) of an IP that are sent to the owner of the network of that IP. ARF has the purpose of create a common format for these advices.

Abuse Reporting Format (ARF) document repository, can be found in, where you can read it's specification.

Hostalia will send Feedback Loops in this format from April 22h, 2009. Owners of the IPs listed on, our blacklist, will be advised using ARF. An example of these messages, where X.X.X.X is the origin IP:

ARF messages from Hostalia will have the Subject as the original email (the spam message) as the draft says. But we add "Abuse Report for IP X.X.X.X:" text to permit easily search by IP, sort messages...until the ARF is RFC and recipients have updated filters and parsers to permit ARF.
