No! According to the article, 5% of email is SPF-tagged. Also,
"Within that 5 percent, slightly more is spam than legitimate e-mail"
5% of email is SPF tagged is misrepresentation. First of all, emails do
not have "spf tags" and as far as amount of email coming from providers
that have published spf records, I would presume that 4.9% amounts to
emails sent by AOL while remaining 0.1% is everybody else...
We do not yet know exact statistics, but I would be surprised if percent
of spam emails that have spf records is anything more then the percent
of spf deployment in general outside of AOL and so far there is no evidence
to support that any major spamhaus is publishing spf records (which would
have greatly increased percent of spam with spf records in the way AOL did
for normal emails)
