ucla.edu have the perfect policy. I refuse point blank to accept any mail whatsoever from dynamic ranges or insane reverse lookups. Why? Because doing so immediately gets rid of 1,000,000+ spam messages PER DAY. Yes, you read that right - a million spams each and every day. The number of users with other ISPs that have valid reasons to host MTAs on DSL is tiny in comparison and they can relay through their ISP (or get a different one that understands mail). Do you have any idea how much that bandwidth costs in a third world country? Or the spam cluster to deal with it? Management agree with that sentiment. Although they did raise an eyebrow a year ago when a colleague blocked ALL of China. They asked him nicely to narrow things down a bit to actual offenders :-) -- alan dot mckinnon at gmail dot com
