Re: [DNSOP] The Larger Discussion on Differences in Response Drafts

please help me get over the feeling that this argument is founded on the
same logic as that used by folks who "know" I might want, no NEED that

Spam being "PUSHED" to the Resolver who may or may not want the data.

Please advise.
