Someone started talking about the risk of having their names and email addresses archived in a publicly accessible mailing list. So I thought I'd ask. In short, the proposal provided for completely removing such data, to protect privacy. See here for more: https://mailarchive.ietf.org/arch/msg/dmarc/fEi0-1NFP-rkrx70Ne1t7fPzldA (There are more threads there mentioning Mailman, in case your ears are burning.)
As an additional bonus, that would also "solve" any DMARC problem.
Is there a FAQ entry for this?
