Thanks, the definition is what I guessed from Jason's response, and tested on my DNS servers. You should have also pointed out section 3.1.1 : "An SPF-compliant domain name SHOULD have SPF records of both RR types. A compliant domain name MUST have a record of at least one type. If a domain has records of both types, they MUST have identical content." No point in discussing if you use TXT or SPF or both, any of those is good, no "deprecated" option. -- René Berber
