AOL happens to be working with the anti-spam community by converting their
MXs to do reject-at-SMTP.  (See SPAM-L archives.  They're quite aware of the
problem and are in fact addressing it.)

Strange; I've received direct SMTP rejections from Hotmail plenty of times
recently.  Given the size of that entity, I'm sure the DNSBL admin in
question would try to work with them (and Hotmail admins have also shown
themselves on SPAM-L); but without any movement, yes, it'd be a candidate
for listing.
