Interesting. There are only two of us users at this domain and the overwhelming majority of incoming messages are spam that's rejected by postfix. We probably average 300 incoming messages per day (mostly on technical mail lists), but have thousands of rejections.
Matt, The three criteria for free use are: 1. Your use of the Spamhaus DNSBLs is non-commercial, and 2. Your email traffic is less than 100,000 SMTP connections per day, and 3. Your DNSBL query volume is less than 300,000 queries per day. They define non-commercial as "A company that uses our DNSBLs solely to filter their own email qualifies as a non-commercial user and may use our free public DNSBLs if that company's email volume and DNSBL query volume is below the free use limits. The same is true for any non-profit organization, school, religious organization, or private individual who operates their own mail server." IIRC, the highest volume shown for a single day was about 10,000 messages; those were rejected by postfix and a few hundred were accepted. That's well below their limits. Rich -- Richard B.
