Not another infected PC or BotNet sending me spam... Well, maybe if you blocked the RATS at the SMTP level of your server, this would not be a problem. We have several lists of IP Addresses that have all the indicators of being RATS, and you can use them just like any of your favourite RBLs.
(However if you are a large email provider (e.g. > 5000 mailboxes) or you are selling/providing commercial spam protection you should be contributing to this effort. We do reserve the right to refuse access without a subscription for those types of companies. For subscription information and costs, please visit our Subscription page for more information.)
