Are there domains that have actually defined SPF record type records? I haven’t been able to find any, but it could be the fault of the tools I’m using.

Jeremy, I really like to use the following wizard to generate my SPF strings: http://www.openspf.org/ Scroll down to the section that says "Deploying SPF", enter the domain name, and click "GO". Then, on the next page, fine tune the answers to the various questions before submitting the info to generate your SPF string. Finally, go into your DNS server and, for that domain, add that string as a TXT record. *and* as an SPF record type, the TXT method is deprecated, but for time being it's good to use it since there are a lot, and I mean a LOT of outdated DNS servers around that do not support it even today, yes, the fault of the DNS server admin for running antiquated rubbish, but, there's just no telling some people to get with the times.
