Summary: Disable rfc-ignorant.org

Bug #6525 proposes disabling NJABL in the default ruleset because it is the
poorest performing DNSBL. Its extremely tiny hit rate is not worth the cost of
a network query.
This is to open discussion of the second poorest performing DNSBL,
rfc-ignorant.org.
http://ruleqa.spamassassin.org/20101225-r1052760-n/DNS_FROM_RFC_DSN/detail
50_scores.cf:score DNS_FROM_RFC_DSN 0 0.001 0 0.001 # n=0 n=2
Poor hit rate, and we apparently don't give it a score because it is unsafe.
http://ruleqa.spamassassin.org/20101225-r1052760-n/DNS_FROM_RFC_BOGUSMX/detail
50_scores.cf:score DNS_FROM_RFC_BOGUSMX 0 1.464 0 1.668 # n=0 n=2
Very poor hit rate, but we do give it a score.
I believe we should disable this in the default rules because this very poor
hit rate and score addition is not worth the extra network query. This rule
should be an option for sysadmins to enable manually if they really want it.
This proposed change would have very little impact on spamassassin's outcome,
but it would free up a network query that could be used for something else more
productive.
