Hi,

I meant that browsers don't let one use some native API to make DNS requests that follow local policies and configuration.

Using DoH for this works, but I see obstacles in using that on a larger scale in a web email client.

People probably wouldn't like their web email client sending requests to CloudFlare about their emails or having to configure their web client's resolver. Nor would they like to get accused of bypassing some corporate DNS for example.

So some alternative approach that would pass on this trust or the required information for establishing this trust in a more universal way would be preferable.


Best,
Taavi

Pure javascript using DoH requests to verify.

Browsers don't allow that though.
