- XML doesn't belong in DNS (not in a non-XML based DNS anyway - and
that's what we have today and tomorrow)
- Whether it is XML or not, SPF-Layer-2 extensions may require policy
data that is to large for DNS.
- Fetching policy data via HTTP is bad because MTA's don't do HTTP -
but they do ESMTP.
What about adding a new command to the ESMTP protocol in order to fetch
policy data that is to large for DNS?
v=spf2 fetch=mail.myserver.com/mylayer2policy mx -all
Does something like this make any sense?
