We are a rural ISP. We were black listed on MANY blacklists when a user violated usage policy. We removed the user from our service and requested de-listing on all 94 blacklists. All but SORBS had us de-listed in 24 hours. SORBS doesn't even answer in their own ticketing system. Fortunately, gmail, msn, live, outlook, aol, etc. do not use SORBS. Unfortunately, Yahoo does. So no mail is going to yahoo at this time and it has been 5 days. I have petitioned yahoo to stop using and irresponsible service SORBS. The entire point to of black listing is slow SPAMMERS and SORBS fails to see tht the ISP and SORBS is on the same damn team. SORBS is actually costing us money is customer loss.
