Hi, @paulcrabtree, and welcome to the Netlify community site. I did find an SPF record which was not working.
The usual workaround for a non-working record is to delete the record and recreate it.
New records should work immediately. Changed records will be affected by the time to live of the previous record (not the current one). This won’t apply for records which should exist and don’t however. Non-working new records should appear when they are created or as soon as they are deleted and recreated if they don’t work as they should.
All records are working now when I test. If there are still non-working records when you test, please reply with the details to identify the non-working record and we’ll be happy to take another look.
If there are other questions or concerns, please let us know with a reply anytime.
