Does MaraDNS have support for SPF?
SPF, or sender policy framework, is method of using DNS that makes it more difficult to forge email. MaraDNS has full support for SPF, both via TXT records and, starting with MaraDNS 1.2.08, via RFC4408 SPF records. SPF configuration is beyond the scope of MaraDNS’ documentation. However, at the time of this FAQ entry being written (June, 2006), information and documentation concerning SPF is available at http://openspf.org. The BIND examples will work in MaraDNS csv2 zone files as long as the double quotes (“) are replaced by single quotes (‘). For example, a SPF TXT record that looks like example.net. IN TXT “v=spf1 +mx a:colo.example.com/28 -all” in a BIND zone file will look like example.net. TXT ‘v=spf1 +mx a:colo.example.com/28 -all’ in a MaraDNS zone file. MaraDNS version 1.2.08 and higher can also make the corresponding SPF record, which will have the syntax example.net. SPF ‘v=spf1 +mx a:colo.example.com/28 -all’.
