False. It just means that I get to choose the method of spam filtering
rather than having my ISP choose it for me.
You're assuming that your spam filters will work better than the DNSBLs you
dislike. Experience with real mail systems (see papers at CEAS) strongly
suggests that the error rate of a well run DNSBL is no worse and probably
better than whatever you think you might like better.
Your "experience" with what you think of as "real email systems" doesn't mean
jack when it comes to my business.
