I agree that using new DNS record types, which requires changes to DNS clients and servers in order to be useful, would be a significant barrier to adoption. My own preference is to store the new information in TXT record(s) in a distinguished subdomain. For example, one might use the TXT records in the '_rmx' subdomain of the domain in question: rather than querying for the records of type RMX in domain domain.com, one queries for the records of type TXT in the domain _rmx.domain.com. A text encoding issue for the information remains, though XML is an obvious candidate. A final point is that we should remember that it's probable that as we flush out an overall spam deterrence story we'll find that we want more than just the specific RMX info that Hadmut has proposed to be published in DNS. Anticipating that now is worth at least a few brain cycles. _______________________________________________ Asrg mailing list Asrg@ietf.org https://www1.ietf.org/mailman/listinfo/asrg
