Thanks for your response! My server is in EC2, and it appears that URIBL blanketly refuses requests from there. I set up a caching DNS server locally and tried routing my request through that, it was still rejected. Too many spammers using EC2 I guess.
As for your other suggestion, isn't that the point of Bayesian filtering? I keep getting similar messages, training my bayes db on them, and then more get through.
