I would like the ESF to score for the presence of IP on the RBL, rather than rejecting messages immediately (as exim does). I found the EASY_DNS_BLACKLIST parameter in the ESF configuration, but I am not able to locate the list of blacklists that I could define for checking. Where it is? Alternatively, is it possible to configure Exim somehow to check RBL but not to reject the message (only score). I know SpamAssassin has this option, but I'd like to do it a level higher.
