I get alot of spam. A LOT of spam. When you've had a (reasonably) popular web site like mine for as long as I have, you tend to get spam. Thankfully, I have been using a challenge-response authentication system for years and that has kept things under control.
But spammers are finding ways around this, or rather by fooling it in some way, so I now block mail from hosts with bad or non-existent reverse-DNS. I didn't want to do this (80% of DNS is misconfigured) but I get tired of deleting email all day long.
