Doesn't help. AOL uses a proprietary MTA that they have

you'd also need to modify all the other standard MTAs, too. And
don't forget about all those Microsoft and Lotus Notes gateways out
Lets say AOL, hotmail, yahoo all today had a way they
could say "we would like to cooperate in validating source addresses
as at least somewhat more valid than today" and had a mechanisim to
do this with a patch to sendmail/qmail/postfix/zmailer.
AOL uses all sorts of mechanisms to try to detect and eliminate
spam, but I wouldn't want to go into too much detail here.
You could also then start keeping statistics and rate-limit
the callback mechanisim. AOL (and i'm sure others) have done "so,
you want to bulk-mail aol users, sign here". Including this
ability to increase customer satisfaction is in all ISPS
