cbl.abuseat.org should be removed. If it still works at all, it's a subset of zen.spamhaus.org, so it's a wasteful DNS lookup. See https://www.abuseat.org/cutover.html for details.

Also, for postscren documentation, see http://www.postfix.org/POSTSCREEN_README.html (or http://www.postfix.org/POSTSCREEN_3_5_README.html for older versions).
