In my "reject_rbl_client" lines, I've been using: - hil.habeas.com - sbl-xml.spamhaus.org - bl.spamcop.net And in my reject_rhsbl_sender line, I have: - ds.rfc-ignorant.org Additionally, I've got Postgrey enabled, which does a really good job of weeding out the spambot desktops and such. -- Mike Burger http://www.bubbanfriends.org "It's always suicide-mission this, save-the-planet that.
