Postfix implements SPF SRS DKIM DomainKeys SenderID BATV and so on exclusively via plugins. Just like Postfix implements deep content inspection. I don't bake my own bread, and I don't make my own shoes or clothes. Instead, I get them from people who specialize in doing such things. This is how society has been making progress for thousands of years. I expect that this approach is also good for the Internet.
