Ah!
Now I better understand your comments on SPAM-L why you think the
complexity of a designated sender system should be put in the namer
server. :->
While SPF is designed to work right now with unmodified name servers,
there are a bunch of things that a modified name server could do.
For one thing, a name server could provide glue records based on the
SPF record. For example, a trivial SPF record of "v=spf1 mx -all"
could include glue records of the MX information. Glue records could
also be provided for exist: and include: options. Heck, most SPF
options could use glue records.
On SPAM-L, you enquired about the custom name server that does
rate-limiting via SPF (http://pond.gladstonefamily.net/server.pl).
There are many similar things that could be automated in a more
general name server.
While I suspect that SPF isn't the design that you would choose to do,
I think it might still be acceptable compared with starting a whole
new designated sender proposal.
