Urrgh. SPF is as far as I know the only protocol published by the IETF that stores policies at the unprefixed hostname, and that is widely agreed to be a mistake. DKIM and DMARC use prefixes. There's the somewhat separate issue that if the prefixed name has to be a hostname so it can be used in a URI, it can't contain an underscore. R's, John PS: Dave Crocker and I have been working on a prefix registry, but it's a thankless task. _______________________________________________ Uta mailing list [email protected] https://www.ietf.org/mailman/listinfo/uta
