Best to block that in your MTA, it probally already does a RNS.
Ask for help on your MTA list, or read below for fix for broken SA rule:

It is supported in SA, but the rule is broken.
I have already submitted a bugzilla with patches, but nothing has been done on 
sa rules for SA since October 31st.

(SA rules folks, highlight: )
See: http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5750

Put this in local.cf, broken rule in  20_dynrdns.cf (don't fix it there!!!!)

This in 20_dynrdns.cf
header RDNS_NONE    X-Spam-Relays-Untrusted =~ /^[^\]]+ rdns= /

Put this in local.cf:
Sbould be:
header __RDNS_NONE    X-Spam-Relays-Untrusted =~ /^[^\]]+ rdns= /

And then assign the score you want: default is 0.1 (from 50_scores.cf)
Do something like:
score RDNS_NONE   20.0

(yes, the score goes on the RDNS_NONE, not the metarule __RDNS_NONE)

You can confirm the broken rule before and check you fixed it after by su ing 
to the user that runs/owns SA/spamc, and run spamassassin --lint.

Before you will get a complaint about the rule, after it should be fine.
