FYI, AOL published SPF records for themselves very recently.  See
http://spf.pobox.com for more about SPF, and you can query dns for
aol.com's TXT records (perhaps by doing "dig aol.com TXT") to see the
SPF record.  Because my machine does SPF checking, it can distinguish
emails forged to be from aol from real emails from aol, and it rejects
the former without sending a bounce message to the unfortunate
joe-jobbed aol user in the envelope from.
