DKIM combines Yahoo's DomainKeys and Cisco's Internet
Identified Mail, two e-mail authentication technologies
developed separately, which the companies announced in
June they would combine with the intention of licensing
the resulting specification royalty-free throughout the
industry.

"Roaylty-free" does not mean it can be used by everyone.
 Microsoft also promised "royalty-free" use of SID, but it
 turned out that did not extend to majority of open source
 programs (with rare exception of sendmail).

 So don't assume that something like courier-mta or postfix or exim
 would necessarily be able to include support for DKIM spec.


p.s. Of course, this development comes on the heels of two
other methods for e-mail authentication already published
by the IETF as "experimental" RFC's: "Sender Policy Framework
(SPF) for Authorizing Use of Domains in E-Mail" and Microsoft's
"Sender ID: Authenticating E-Mail".
That is false information. They have not been published as "experimental" RFCs, only approved for publication. Publication may come later and yet
may not happen at all.
