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.
imho opendkim can limit body content signing (body length), so if that is limited, all content after that limit will be ignored on verify, its just not very used, but its there
DKIM, SPF and DMARC have one thing in common: they're all hostile to mailing lists.
and i still get dmarc pass here, so even if maillists software is over 20 years old it still does not break dkim, funny part is that software recently trying to solve dkim maillists problems are doing more bad things then solve it
