Debugging SPF records

While debugging a SPF record I found spf-record.de Show archive.org snapshot to be very helpful.

  • it lists all IPs that are covered by the SPF record
  • shows syntax errors
  • helps you debugging errors like DNS lookup limit reached
  • it also lets you test a new SPF strings before applying it. This can save you time as you don't have to loop with operations

Also the advanced check at vamsoft.com Show archive.org snapshot has a very good interface to test new SPF policies.
