This isnt a Cpanel specific question but since we are suddenly seeing ALOT of posts regarding spam I would like to bring up the question of what everyone is doing for reverse dns black lists / RBL's, etc.. like ORDB.org, Spamhaus, etc.. We run many servers and found that once we enabled RBL checking in our servers we saw a tremendous drop in incoming spam. It wasnt a cure-all but it sure did help ALOT. I am concerned however that as we grow we will be using these services more and more and I was wondering if anyone here has switched from the usual free lookups to a paid datafeed. Is there a point when the RBL service providers will cut you off because of traffic/load on their servers?. Anyone here have ALOT of servers which do tens or hundreds of thousands of requests daily with the free lookups or have you switched to a paid feed. If you use a paid feed like Spamhaus what do you pay and do you have any problems with it ?. Thanks.
