I disagree about "very good reasons for footers on many lists". Meta
information belongs into the message headers, not the body. DKIM-signed
messages are letters, not postcards, and no non-totalitarian postal
service would dare open your letter and scribble junk on the contents.
Stick to the envelope, Mr. Postman. ;-)
Scribbling in the body also breaks PGP signatures. At least that's
trivially worked around by adding the list footer in a separate MIME
part as many lists do. But DKIM still doesn't like that.
DKIM, SPF and DMARC have one thing in common: they're all hostile to
mailing lists.
P.S.: We're drifting far away from Postfix here.
Sorry for continuing to drift. I'll shut up again. :)
