SpamAssassin Rule: DNS_FROM_RFC_POST

Standard description: Envelope sender in postmaster.rfc-ignorant.org


The domain of the envelope sender is listed in the DNSBL postmaster.rfc-ignorant.org.

The criteria for listing is that the servers listed in the domain's MX records do not accept messages for the reserved mailbox "postmaster". The basis for this is section 4.5.1 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 3.3.2 (see bug 6526)
