Is Steve Case dancing while AOL burns? E-mail isn't being delivered from, Ziff-Davis News reports -- and it isn't the first time. AOL has unilaterally stopped delivering e-mail from several domains in the past -- including internet services with thousands of users!

At best, it's a mistake. Since AOL's subscribers can't use Eudora or other powerful e-mail programs available to users with internet accounts, they have to rely on AOL to filter much of their spam. Sometimes AOL's judgment is flawed. One webmaster's lawyer reports AOL blocked his site's mail, and then denied that they were doing it!

This lax attitude -- and a pick-and-choose approach to e-mail delivery -- have left an underclass of on-line citizens. The New York Times reports that AOL has come to be known as the internet's lowest caste.
