We just got hammered by something called trustedopinion.com with invitations to visit their website. Nearly 100 of these invitations sailed right through SpamAssassin with the help of two extraordinarily favorable rules:
-8.0 HABEAS_ACCREDITED_COI RBL: Habeas Accredited Confirmed Opt-In or Better [209.237.227.62 listed in sa-accredit.habeas.com] -4.3 RCVD_IN_BSP_TRUSTED RBL: Sender is in Sender Score Certified (trusted relay) [Return Path SenderScore Certified (formerly] [Bonded Sender) - <http://www.senderscorecertified.com>] Surely such trust in them is misplaced? At a minimum, I can guarantee they are *not* "Opt-In or Better". Fletcher
