whitelist_from_rcvd is intended to legitimate a single somain, specifiing domain by domain
I need something that tell me that check all incoming email and say if the originating ip (or class c) is the same of mx record This can be intended like an SPF_PASS when people doesn t set spf at all.

Not quite, but assuming you're looking at using it for whitelisting purposes you can use: whitelist_from_rcvd *@gruppocommet.it gruppocommet.it That says that any mail sent with a @gruppocommet.it address that is received from a host with an rDNS matching gruppocommet.it will be whitelisted. It's rather effective and efficient. https://spamassassin.apache.org/full/3.4.x/doc/Mail_SpamAssassin_Conf.html#whitelist_and_blacklist_options may tell you more.
