Nerd! Nerd! Christian, this might be the all time best blog I've ever read. The only thing more nerdish would be if I started raving about the brown thrasher I saw today. Nerd! Nerd! Nerd!

You've got it. Most legit email does not originate from hosts with lots of digits in the hostname. Conversely, most DSL/cable/dialup hosts have a lot of digits in their hostnames. It was my thought that by filtering email out from hosts with lots of digits in their host names would curb some spam. A DNS blacklist is a list that is contains the host names of known spammers, mail servers that have been compromised and used as spam relays, and (some lists) dynamically assigned addresses. You use a list like this that is maintained by a 3rd party and configure your mail server to reject mail from any host on the list. “Is it just an extension of the idea that a spam server is named in such a manner?”

But while we’re here:
“The idea was to check the amount of numerical digits in a sending machines domain name in a mail header to help determine if it is SPAM”
How does that help? Is it just an extension of the idea that a spam server is named in such a manner?

Also, what is “DNS blacklist?”
