DKIM Production IETF

IETF DKIM Standardization Effort


DKIM was a chartered IETF effort, seeking refinement and standardization of the DKIM specifications.


This group operates according to IETF Policies and Rules for individual participation and for the handling of intellectual property. Claims regarding DKIM technology must be filed with the IETF


The charter states the purpose and workplan of the proposed IETF effort. It applies to the DKIM discussion list.

The ietf-dkim discussion list is the open venue for pursuing IETF-related DKIM discussion. (An archive of earlier, IETF-related DKIM discussions is available for the ietf-mailsig list.)

An online issues list shows items pending in the working group.
