Currently I've got two SPF related web pages on my web site:
http://www.kitterman.com/spf/txt.html
http://www.kitterman.com/spf/validate.html
Just because I'm procrastinating doing real work, I decided to see how much
activity they were getting (total and then the referrer):
Data From: total pobox.com google None/Other
20050802 faq dns mail-list
Visited TXT 28 16 5 7
Visited Validator 63 28 4 4 9 18
-Visited Only 8 1 1 2 4
-Used Validator 55 27 4 3 7 14
My apologies in advance if this table isn't readable. Note in case anyone
is wondering, the actual queries to the validator aren't logged. Only the
usual http: web log type stuff.
