I would certainly agree with that. There's a summary of all the mitigation techniques I know here: http://wiki.asrg.sp.am/wiki/Mitigating_DMARC_damage_to_third_party_mail If I've missed any, drop my a line and I'll send you a password so you can edit the wiki. On my lists, I'm currently rewriting stuff from DMARC'ed domains to use forwarding addresses. So if a list message is from, say, From: Marissa <mme...@yahoo.com> It rewrites it to: From: Marissa <mme...@yahoo.com.dmarc.fail> It locally arranges for that address to forward back to the original one for a few days, and adds an appropriate DKIM signatures. It was all surprisingly easy to do, about 100 lines of python and perl.
