Here's an idea that I'm thinking about in my fight against spam. DNS lookup of hostnames that NEVER send spam. That way you can make sure that some good email is never misclassified as spam. And you can reduce the load on Spam Assassin or other expensive filtering by bypassing spam testing.
That are a lot of servers out there than never send a single spam. So - why not track them and build a DNS whitelist server to distribute the lists? Stop me if it's been done already. Then - I'm also working on the idea of a second white list of hosts that should never b accidentally blacklisted. The idea here is to prevent hosts that send some spam, yahoo.com, earthlink.net, from ending up in a blacklist. This will make it so that the blacklists have less falso positives. So - who likes this idea? -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
