Subject Bogus day old domains from RRPPROXY.NET
Date Thu, 19 Feb 2015 19:50:17 GMT
Lately we've been getting slammed by spam.  The bulk of it (no pun intended) is coming from
new domains (many just a day or two old) which originate from key-systems gmbh, and all use
RRPPROXY.NET as their name servers such as this snippet from whois:

   Registrar: KEY-SYSTEMS GMBH
   Sponsoring Registrar IANA ID: 269
   Whois Server:
   Referral URL:
   Name Server: NS1.RRPPROXY.NET
   Name Server: NS2.RRPPROXY.NET
   Name Server: NS3.RRPPROXY.NET
   Status: ok
   Updated Date: 19-feb-2015
   Creation Date: 19-feb-2015
   Expiration Date: 19-feb-2016

The Day Old Bread rules don't seem to catch them.

My scores for this are:
SpamAssassin Score:	4.71
Spam Report:	
Score	Matching Rule	Description
5	required	 
-0.00	BAYES_20	     Bayesian spam probability is 5 to 20%
2.50	CBJ_Dementia	Mail with dementia
1.50	CBJ_Sicko	     Disease related spam
0.00	HTML_MESSAGE	HTML included in message
0.72	MIME_HTML_ONLY	Message only has text/html MIME parts
-0.00	SPF_HELO_PASS	SPF: HELO matches SPF record
-0.00	SPF_PASS	SPF: sender matches SPF record

Is there a way to reject or up the score on anything that is served up by that name server
or registar?  I was thinking maybe putting the nameserver in my dns as,
on the theory that if it doesn't resolve the message will be rejected at the MTA level.  It
would be nice to have a bit more control over it, just in case however.  Any pearls of wisdom?
