Except that addresses from the Static pools are typically given to customers of the "small business" packages, specifically for the purpose of running their own servers. (For cable operators in the US, that is basically the only difference between the residental and the small business packages.) So what you're really saying is, "They've got a hostname that looks like a small business, and a small business shouldn't be connecting to other people's mail servers." Now, some of the ISPs do let residential customers pay extra for a static address. But I'm willing to wager that anyone who's paying extra for a static IP is going to be smarter than the average bear, and not let themselves get zombified. I like what you've got so far (though I haven't put it on my own server yet...looking for more feedback from others first), but I disagree with adding "static" to the keywords.
