Warning: Failed to lookup DMARC even when Organizational domain policy found

[reevesjeremy]

Subdomains that dont have their own DMARC policy record automatically inherit the DMARC policy from its parent. exo is already handling that lookup, but is also throwing "Failed to resolve" warnings

I think before the the DMARC function logs a lookup failure, it should chase the domain tree to find if a record is published for a parent domain, and only throw the Failed to resolve warning if there is also no parent DMARC policy. Otherwise the warning is distracting and misleading.

Thanks again for this report. I've opened #1479 to track the underlying issue.
