I believe you're right on every count. I did, however, place an explanatory webpage on the mta reject message, so that the sysadmins on the verge of acquiring a clue can have the problem fixed.

    AOL only started about a year ago, I've been doing it for over 5 or 6 
    years, the results speak for themselves.
    If you run a network where the system admins are incompetant and do not do 
    their job properly by ensuring every host has a hostname, be it dsl, dialup,
    a hosting server or a key server in a NOC, its just plain lazyness, and 
    they should be dismissed as such.
