	What AOL does now will no longer work at all with BINDv9.  IMO, 
it's long past time.

	After the problem I previously mentioned (where I was personally 
blamed for taking out all e-mail throughout the entire world, due to 
the 19-hour downtime during AOL's "Black Wednesday" failure), I had 
actually fixed this problem with mechanisms that were a little 
strange, but perfectly legal according to the RFCs.

	However, after I left AOL, someone apparently decided to go back 
to the old mechanism which violates the RFCs (it points MXes at CNAME 
records).  Fortunately, a good friend of mine is now in charge of the 
DNS at AOL, they're starting to use the BINDv9 tools to validate 
their zones, and maybe I can convince him to fix this problem with a 
more appropriate mechanism.
