How To Implement Domainkeys In Postfix Using dk-milter

Post date: February 5, 2008, 12:02 Category: Network Views: 5500 Comments
Tutorial quote: Domainkeys is "a method of e-mail authentication. Unlike some other methods, it offers almost end-to-end integrity from a signing to a verifying Mail Transfer Agent (MTA).

So why a how to on it when there is DKIM? Well domainkeys is still actively being used and is more widely deployed than DKIM, the developer Yahoo still uses it to sign and verify mail although they are contributers to the DKIM standard.
