The _BEST_ resource (IMHO) I've found anywhere regarding RBLs, Block lists, etc. is at:
http://www.declude.com/JunkMail/Support/ip4r.htm It has commentary on EACH of the RBLs with any warnings, cautions, etc. which is useful for deciding which to use. Hope that helps! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
