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. -- William Leibzon Elan Networks [EMAIL PROTECTED]
