Hi, Keith. My spam filters catch about 70,000 spams a day, mostly
using DNSBLs, with a false positive rate well under 1%. If you're
offering to sort them, and can promise a similar error rate, I'll
send them along.
If not, I'd appreciate it if you'd explain exactly what operational
advice you're offering here.
