Comcast is known to emit lots of abuse -- are you blocking all their networks today?
All? No. But I shouldn't find it necessary to block ANY, and wouldn't, if Comcast wasn't so appallingly negligent. ( I'm blocking huge swaths of Comcast space from port 25. This shouldn't really surprise anyone; Comcast runs what may well be the most prolific spam-spewing network in the world. I saw attempts from 80,000+ distinct IP addresses during January 2007 alone -- to a *test* mail server. I should have seen zero. The mitigation techniques for making that happen are well-known, have been well-known for years, and can be implemented easily by any competent organization.) This, by the way, should not be taken as indicative of either what I've done in the past or may do in the future. Nor should it be taken as indicative of what decisions I've made in re other networks. ---Rsk
