**Enable Spamhaus URL blacklist**: If enabled, URLs will be checked against the Spamhaus DNSBL. The `Spamhaus Project <http://www.spamhaus.org>`_ provides a URL blacklist that is free for non-commercial, low-traffic use. A professional use datafeed service is also available but not supported in Mahara. Please read the `Spamhaus DNSBL usage terms <http://www.spamhaus.org/organization/dnsblusage.html>`_ before enabling this option.
