== SpamAssassin Rule: DNS_FROM_RFC_DSN ==

''Standard description:'' Envelope sender in dsn.rfc-ignorant.org

=== Explanation ===

The domain of the envelope sender is listed in the DNSBL 
[[http://www.rfc-ignorant.org/policy-dsn.php|dsn.rfc-ignorant.org]]. 

The criteria for listing is that the servers listed in the domain's MX records must accept messages with the empty sender address (MAIL FROM:<>) so that Delivery Status Notification (DSN) messages can be delivered.

=== Further Info ===

The default scores for this rule can be found [[http://spamassassin.apache.org/tests.html|in the online list of tests]].
