The mailing list for listmasters using Sympa

[Adam Bernstein <address@concealed>]

Well, at least I'm happy to see we're not flailing alone in this DMARC 
mess, and the John Levine piece was particularly reassuring - will Yahoo 
perhaps back down from this new policy?  (Too much to hope?)

I'll chime in here:

Nope, it's not - we've done that since we implemented DKIM, and the 
DMARC test is failing for us because the domain in the DKIM signing 
(like @groups.electricembers.net) doesn't match the sender's domain 
(@yahoo.com).

I believe X-Original-Authentication-Results is the only way out that 
preserves our current scheme, but we haven't yet figured out exactly how 
to implement that, or if we can at all.
