You may be pleasantly surprised to find out you do qualify for free use. http://www.spamhaus.org/organization/dnsblusage.html *Definition: "non-commercial use" is use for any purpose other than as part or all of a product or service that is resold, or for use of which a fee is charged. For example, using our DNSBLs in a commercial spam filtering appliance that is then sold to others requires a data feed, regardless of use volume. The same is true of commercial spam filtering software and commercial spam filtering services. If you're non-commercial, and at less than 100,000 SMTP transactions per day, and less than 300,000 dnsbl queries per day, then you qualify for the free service. -- Stan
