fake domain, and publish +all SPF records for it. Except that he just tied
himself to that domain. And that is costly. Because instead of sending out
addies with the AOL domain, he must now use his own domain(s). And that will
get him blacklisted a lot sooner.
...basically forcing him to use "disposable" domains. That is, many spammers
might do just that - use a domin *once* for a single big spam run, and not
care if the domain gets backlisted a few days later.
