Sorry, *unlike* the rfc2822 flavor.  That flavor uses a hash of the
message header and body instead of an incrementing serial number.

Probably doesn't work due to message munging during forwarding.

It works as well as DKIM since it uses the same scheme.  The most
common type of munging is adding mailing list footers, but that's
remailing with a new MAIL FROM and has nothing to do with
forwarding.  If a mailing list does not use this rewriting scheme,
the crypto token in the original MAIL FROM automatically goes away.
If the mailing list does participate, then it creates its own
crypto token, with a new hash for the munged message body, when it
makes the new return-path.
