ARF

What is ARF?

  • ARF- Abuse Reporting Format.

ARF is intended to standardize Feedback Loop emails. This effort will help prevent feedback loop recipients from requiring multiple parsers for various mailers' FBL reports. AOL uses ARF as its only FBL format.

What is the difference between the old AOL Feedback Loop format and ARF?

The traditional format is a MIME multipart message with one empty text part and one message/rfc822 part with the original message being complained about. Parts of the header of the message being complained about are redacted out, where normally the AOL ScreenName recipient would be present.

ARF is defined in draft form at the IETF. ARF messages have three mime parts, one part for general information, one machine parsable and meta data part, and the last part as the original message being complained about. The original message is redacted to protect clear text occurrences of AOL screen names and email addresses.

ARF is designed to be machine readable and assumes that parsing and decoding complaints will be done via scripting. However, ARF can be read in most major email clients with a little human intervention. See our blog entry for more details.

Please do not contact AOL for assistance in reading ARF complaints. We've invited solution providers to advertise in our blog comments and welcome you to look there for help. Please note that AOL has not tested these solutions and does not endorse any particular vendor or product.

What is there to note about the AOL implementation of the Abuse Reporting Format?

AOL will not fill the Reported-URI field in the second mime part. ARF messages from AOL will have the Subject as defined in the original draft, with the connecting IP shown, and not the original subject of the email being complained about.
