Re: [ietf-dkim] NEW ISSUE: Discussion of query traffic overhead

The comment you quote expresses rather a different concern: that the
additional traffic associated with lookup of messages with a valid
signature which is not an Originator Signature will be excessively
burdensome. Can you explain what will lead to the generation of large
volumes of mail signed by other than the Originating Domain? Even so,
we're only talking about 3 lookups maximum.

There are currently quite a number of queries that will almost always
fail for a significant number of years into the future: AAAA queries.
This isn't meant as a criticism of IPv6 deployment, but I haven't  
heard
that DNS is melting down as a result, either.


I agree with you, Jim. I don't think it's going to be an issue. But  
the fact that the analysis will be easy and affirmative doesn't mean  
we don't have to do it.
