Speaking as someone who hosts a couple of dozen email lists, I
really don't understand what the fuss is about here.
The fuss involved people having paid no attention to the announcement of
Dng's DMARC-mitigation munging starting on December 6th, and so being
confused by that and the appended Reply-To. And some people, including
you, still aren't getting that, even though it got re-explained
yesterday, encore une fois.
Ahh... missed that. Didn't really notice anything until this huge
string of emails. Sigh...
If one runs a list, and wants folks on gmail, AOL - any service that
honors p=reject - then one has to:
1. adjust headers so that list mail appears to originate from the
list manager, not from the original author
Yes. But only where p=reject or p=quarantine..
Yes, indeed.
2. publish DKIM & SPF records for the machine hosting the list
No, there's no obligation for either of those, to ensure deliverability
of mail munged by the MLM software for DMARC-mitigation purposes.
True, but it sometimes helps. And it's easy enough if one has access to
one's nameserver records, as anyone who runs a list manager usually does.
Updating the mailman settings, and publishing the appropriate DNS
records, is really a no brainer for any halfway competent list
administrator.
Indeed, the Dng listadmins did exactly that, on Dec. 6th, following
instructions I provided. The whole thing was covered here at the time,
so I'm puzzled that so many people seem to have failed completely to
read the explanations.
Sorry to add to the noise - there was just so much of it. My bad.
Cheers,
Miles
