I'm experiencing a strange problem with RDNS_NONE. On the same sender host, sometimes it is marked with RDNS_NONE, and sometimes not.
The host has a reverse dns! Example: Received: from dadosoftware.com (dns2.dadosoftware.com [217.199.13.2]) -> OK Received: from dadosoftware.com (unknown [217.199.13.2]) -> FALSE POSITIVE But 217.199.13.2 has a reverse dns! 2.13.199.217.in-addr.arpa. 11894 IN PTR dns2.dadosoftware.com. Who decides the presence of RDNS_NONE ? A real dns check or a parsing of the email headers? And, in case of parse who decides to write dns2.dadosoftware.com [217.199.13.2] instead of unknown [217.199.13.2]? Thanks to all in advance. -- /*************/ nik600 http://www.kumbe.it
