Members of the DMARC group have submitted two drafts
draft-andersen-arc-00 and draft-jones-arc-usage-00 which describe a
mutation of DKIM intended to let mailing lists coexist with DMARC
without having to do ugly hacks like rewriting the From: line.  I have
reason to believe that several large mail systems intend to implement
this reasonably soon.

The obvious place to discuss this is the DMARC WG, not here.

R's,
John
