If Pine adds Mime-Version header, that means its MIME email and if you're
sending to application that does not handle MIME, you should not be doing
it
Sorry, that's completely wrong. MIME is carefully designed to
interoperate as well as possible with non-MIME applications. Pine sends
mail flawlessly to recipients that don't do MIME, because one of the few
things that even primitive MUAs and MTAs do reliably is to ignore headers
they don't understand.
As far as your protest about possible problems for devices that cant
handle MIME, I do not think its a strong point and I'm guessing it would
apply to less then 0.0001% email messages. In fact I'm betting it would
apply to 10,000 less cases than if we use your preferred DomainKeys
which signature breaks with all mail lists or if we use SPF which breaks
forwarding (but forwarding servers are more central and easier to upgrade
then all mail lists).
I am 100% sure that you are pulling your numbers out of thin air. When
you have some real data, please let us know.
By the way, if you think that MIME will magicially preserve MASS
signatures through mailing lists that rewrite subject lines and other
headers and add footers and other junk to message bodies, you have a lot
more faith in its powers than I think is warranted.
