We could, but it's not actually a requirement that the SDID resolve
in the DNS (and in many cases it won't).
Really?
Then how does the receiver obtain the public key for performing
verification?
key retrieval is defined as using d=.
If you receive an email with a selector of banjo.aardvark and an SDID
of hatstand.beartrap.blighty.com then you'll hopefully be able to
resolve banjo.aardvark._domainkey.hatstand.beartrap.blighty.com, but
that's all you can say about ability to resolve any query in the
domain tree under the SDID, including the SDID itself.
At least, that's how I understand it.
Cheers,
Steve
