Here are a few SPF tools which I recently used.
- http://www.openspf.org/Tools – an email based tester
- http://tools.bevhost.com/spf/ – web based tester
- http://www.mailradar.com/spf/
- http://www.mtgsy.net/dns/spfwizard.php – a wizard for setting up SPF
– wizard to create SPF records
I needed to alter some of my SPF records because they were out of date, and therefore, no longer accurate.
