Topic: RDNS_NONE hitting all the time
I have a small problem with the RDNS_NONE rule in spamassasin, it's hitting all the time (at least almost all the time), even if the partner server has proper name -> address -> name resolution.

outbound-mail-359.bluehost.com -> 22.214.171.124 -> outbound-mail-359.bluehost.com, so the name resolution is consistent.
According to spamassassin wiki, there always is checked the last untrusted relay. So, what is wrong in this case? Why it isn't working?
