As a concrete example, if I wanted to include the authenticated
age of each email sender (something the gambling industry might
be interested in) then I can do that within the DKIM signature:
DKIM-Signature: v=1; d=corp.example.com; <blah>; db=19700224
Actually, what you want is a gerenal purpose txt or comment header, in
which the signer can place any remark that he considers worthy of his
signature (including the capacity in which he is adding his signature -
another feature that people argue about).
E.g. DKIM-Signature: v=1; d=corp.example.com; <blah>;
tx="birthdate=1970-02-24"
or DKIM-Signature: v=1; d=corp.example.com; <blah>;
tx="signed by List Expander"
I suppose such a tag would have to be an extension to avoid recycling at
