The issue with MARF inside IODEF is that the receiver needs to know that the payload being provided inside an EmailMessage element is itself an ARF report, and not the message that caused the report in the first place. You certainly could crack open the EmailMessage content and see if conforms to the ARF specification to tell which kind of report you've gotten, but that seems inelegant.
I suppose then another option is an extension element that indicates you've received an ARF payload rather than the actual offending message. Also of note: An ARF can contain the offending message or only the offending message's header, and still be compliant. If your application needs the whole message, you'll have to add some additional stipulations someplace. -MSK On Fri, Mar 1, 2013 at 1:52 PM, Panos Kampanakis (pkampana) < [email protected]> wrote: > I think MARF provides more functionality and should be leverage for emails > in IODEF. > I also think we need to resurrect > http://tools.ietf.org/html/draft-vesely-mile-mail-abuse-00 within MILE > since MARF was concluded.. > Panos > > > -----Original Message----- > From: [email protected] [mailto:[email protected]] On Behalf Of > Moriarty, Kathleen > Sent: Thursday, February 21, 2013 5:19 AM > To: [email protected]; [email protected] > Subject: [mile] Including Mail fields in IODEF > > Hello, > > Cross posting with MAIL and MARF - > > In MILE related work, I have come across use cases that would like to > include DKIM and SPF information in addition to specific mail fields (like > the ones Chris lists below).
