SpamAssassin Rule: URIBL_RHS_DSN

Standard description: Contains an URI listed in dsn.rfc-ignorant.org

Explanation

The message contains a URI whose domain is listed in the DNSBL 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. The basis for this is section 5.2.9 of RFC 1123 and section 4.5.5 of RFC 5321

Further Info

The default scores for this rule can be found in the online list of tests.

This rule is disabled in SpamAssassin 3.3 (see bug 6526)

As of October 2012 this DNSBL will be unavailable.
