Next I need to find a way to send automatic bounces back to people trying to send mail to aol.com address via my servers telling them that AOL has, effectively, decided to disconnect its e-mail system from the rest of the Internet and if they want to send mail to AOL, to switch their SMTP servers back to their ISP's!
Wait! Before you do that, take a look at all the other ISPs that are now moving into this type of environment. The numbers are staggering the more and more I read. This is not just AOL, this is all major ISPs or any ESPs (Email Service Providers).
