Only around 15 percent are @aol.com addresses but unfortunately AOL has 
other domains such as @netscape.com, @bigfoot.com, and possibly others, 
all of which get handled by the AOL postmaster. I don't have an 
exhaustive list; while it's mostly likely some user in @aol.com-land, I 
can't say for sure.
