SpamAssassin RBL details

SA runs RBL checks on all the IPs in the received headers except for
hosts on "trusted networks".  In case you were wondering, Mailscanner's
built-in RBL checks only check the connecting IP and thus aren't
appropriate for your config (unless Julian's changed them recently).
You should be fine using SA's RBL checks.
