I don't know. It is more like you own a brand of shoes that won't let you untie them to take them off. Honestly if you could see how much horrific spam comes through the AOL gateways you would see that there are so few options to stop it all. Look at it this way... Many spammers use dialup, DSL, and cable. If a spammer asks their ISP to change their rDNS then the ISP will wonder what that customer is up to. If they are a legit business then the ISP should let them change it. On the other hand you have zombies and open gateways all over the internet hanging off dialup, DSL, and cable where the machine just sits and spams constantly. The filtering AOL is doing on rDNS stops -all- of that spam because those zombies and open relays that are just machines setup without much thought won't have rDNS set to something other than the default. Now also think about viruses that are mass mailers. AOL stops those dead by this filtering. They can't get in because they have the default rDNS that has cable, dsl, or dialup in it. That works for us even when a virus is brand new and in the wild. You can't beat that kind of blocking. So now the only spam coming in to AOL is from machines where rDNS has been setup and one can assume it is a business of some sort. These people we can take legal action against and stop their spam. These are about the only people we actually can hunt down and slap a lawsuit on. The spam / virus front is hard when you scale it to millions of customers. This solution is a smart one IMHO even if it does hurt some non-spammers at first. If your provider allows you to run a server and they don't let you change rDNS when you explain that AOL is blocking all servers with certain keywords in rDNS then your ISP is doing a serious dis-service to you and you should complain all the way up the support tree until you hit management at the ISP and calmly argue your point. -Josh To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
