Does hotmail use ARF for its feedback loop message?

Question

I am working on a program to parse ARF (Abure Reporting Format) messages. It turns out I need to be able to handle Hotmail feedback loop messages as well.

Does hotmail use ARF for its feedback loop message? If not, which format is it using?

I found this site providing a perl parser to convert hotmail messages to ARF format which make me think it is not using it.

I read somewhere it was using JMR (Junk Mail Reporting) but I can't found any example of such a message on the Internet.

Answer 1

No, unlike e.g. AOL Hotmail doesn't use the ARF. Instead you'll get emails with the subject "complaint about message from [ip]* from "staff@hotmail.com", which contain the original body.

Answer 2

Microsoft, as usual, has come up with their own proprietary alternative to the standard (at least they're consistent, I guess) called JMR - Junk Mail Reporting.
