Unless you have some specific reason to be concerned about accidentally starting an unrelated TXT record with "v=spf1 ", I can't imagine you don't have more important things to worry about. This being a "problem" is a great theory, but it just doesn't happen in practice. > SPF validators MUST NOT proceed to a TXT lookup on SERVFAIL for SPF. > This is similar to not proceeding to A/AAAA lookups on MX lookup > failures. Except that it's quite common for a SERVFAIL on TYPESPF to occur for a domain that has an actual SPF record due to various operational issues. SERVFAIL on type SPF doesn't reliably tell you anything about what a type TXT lookup would produce. So it's similar, but only superficially so. > I would also suggest that there be a sunset date published for the > use of TXT for SPF. Do you also suggest creation of an Internet police force to enforce this? What would be be mandatory minimum sentence? Scott K
