We've had customers asking us for a simple SPF wizard to help generate Sender Policy Framework (SPF) data. There are a few out there, but we have set up one at wizard.easySPF.com or spfwizard.com.
As we iron out any usability bugs we will roll out some integration hooks to make it easier to pull the output from the wizard into your zonedata, but for now it's the old cut-and-paste.
