Aye, looks like their goal is to list all commercial senders, legit, semi-legit, or otherwise. Which I could see being useful in some environments. (ie: certain commercial environments where email use is tightly restricted anyway) I find it interesting that on their statistics page, they reference the percentage of emails blocked (60%), but have no criteria for examining the number of false positives... If high block rate is good, well, shutting down your mailserver is even better, 100% block rate! :) Not to say the list doesn't serve a purpose, but I do find the quoted statistics on the website a little lacking in useful value. I also find it disappointing they've got with a bunch of custom (patent pending) software called BMS to essentially be the functional equivalent of rsyncing DNS zones once a day and locally hosting them on your DNS resolver. (or at least it appears so) At least some of the comparison below is only valid for a off-site, non-rsynced RBL: http://www.mipspace.org/rblvsbms.php BMS might be more efficient than rsync/local dns, but it is hard to tell how much better it really is without any basis of comparison that's not based on remote lookups. As a result of the customization they only support 3 MTAs (notably no sendmail or exim support) http://www.mipspace.org/mailservers.php
