Hi all, we are aiming to provide free usage of our DNSBL to the general anti spam community as soon as possible. However, in order to do this we would need to deploy more DNS mirrors or we risk providing a poor service due to the amount of DNS traffic we expect to receive. If you think you are up to this (or you know someone that would be) and you have the necessary infrastructure and bandwidth to support a rbldnsd mirror, please contact me off list so we can discuss details.
This DNSBL has been running for a while now, incorporated in the SpamAssassin weekly mass checks and isn't exactly new (we've been operating since Feb 2008). What's new is the "free" part of it. You can check the current results here (last two weeks): http://ruleqa.spamassassin.org/20100220-r912093-n/%2FRCVD http://ruleqa.spamassassin.org/20100227-r916929-n/%2FRCVD The relevant rule name is "T_RCVD_IN_ANBREP_BL" (aggregation of all bad reputation IP addresses). Note that both the rule name and the DNS zone in use will change to a dedicated zone (which is already up and running). If you want to test it out use this one instead: http://mailspike.org/anubis/implementation_sa.html . At the moment our goal is to get enough mirrors to provide a free sustained service and an overall good experience to SpamAssassin users, so that in the future this can be included in the SpamAssassin base rules (assuming of course SA folks would see value in it). All the best, --- João Gouveia
