SpamAssassin Rule: DNS_FROM_RFC_WHOIS
Standard description: Envelope sender in whois.rfc-ignorant.org
The domain of the envelope sender is listed in the DNSBL whois.rfc-ignorant.org.
The criteria for listing is that the domain does not possess a public whois server as specified in RFC 1032, meaning that contact information for the domain administrator cannot be determined using standard tools.
The default scores for this rule can be found in the online list of tests.
