I'll cheerfully give up references to S/MIME, if other people will
give up on telling software developers how to rewrite MLMs to do
things they've never done before.
Frankly, the best possible advice we can give is to tell people to
sign all their mail, set ADSP to discardable and let mailing list
mail get to sent to the trash can. If that doesn't get the hidebound
traditionist over-entitled mailing list developers and operators
attention, they pretty much deserve dying along with their 1970's
view of what the internet is.
