What's up with DKIM Email
The DKIM working group in the IETF has been making good progress. We now have a draft of
an overview document as well as an updated and, with any luck, final version of the threats document. The main spec for DKIM signatures seems to be close enough to done for a "last call" for complaints and comments.
