In a desperate attempt to ensure DKIM can secure IPv6 SMTP sessions, a
request to change the SSP draft has been limited to mostly just the
Author Signature definition:
5. Recommended Changes
5.1. 2.7. Author Signature
CHANGE:
An "Author Signature" is any Valid Signature where the identity of
the user or agent on behalf of which the message is signed (listed
in
the "i=" tag or its default value from the "d=" tag) matches an
Author Address in the message. When the identity of the user or
agent includes a Local-part, the identities match if the Local-parts
are the same string, and the domains are the same string.
TO:
An "Author Signature" is any Valid Signature per section 3.2, where
an Author Address domain is within the signature's "d=" tag and
value
domain.
The basis for a challenge could be an unsafe violation of the WG
charter. Although those within the WG represent talented and
competent individuals, one might reasonably suspect the WG is biased
to favor the interests of the large domains. The SSP draft, as it
currently stands, does not best serve the general interests of the
Internet as a whole or help usher in an era of IPv6.
