A list of SPF record generators

CloudFloor DNS has a free SPF Wizard that allows you to generate your own Sender Policy Framework DNS TEXT or caller id records that you can add to your own DNS zone files. According to the service, it looks like the SPF records generated should work with most DNS services that accept TXT or SPF type records.

All you have to do with this SPF wizard is answer some questions, and then press a button to get an SPF record to add to you DNS record.

This particular SPF record generator gives you a fair amount of options.

I also mentioned the free SPF record generator from Microsoft. It can be found here. It's really easy to use and is not very complicated for the novice to figure out.

An SPF record generator created by Roy Hochstenbach and which is easy to understand is available here. There's even a link at the bottom of that page where you can download the source code so you can run Roy's SPF record generator on your own server.

This one's nice. An AJAX enabled SPF record creator. It generates your SPF record as you type. Really good if you want to see the changes made in your SPF record right away. It might help people wanting to understand the syntax of SPF records. This is one of my favorites. It also allows you to choose which DNS server syntax you'd like the resulting SPF record in - Bind or Tinydns.
