I used viewdns.info - allowed me to search by registrant name. I looked for Bed Bath Procurement and Liberty Procurement for the list I grabbed (~600 results). Spotted the .sex TLD and filtered down to that and hand-verified whether each result was truly owned by BBBY. I work in IT Audit and InfoSec, so was a piece of cake to find and filter the data. :D.

I am quite new to the whole topic of email security and today I came across whatsmydns.net and searched for my domain. Since then I realized that some DNS records are open to the public (e.g. Verification and SPF) and others maybe are, too (at least not on this website, couldn't get information about my dmarc entry).

However, after over 4 days whatsmydns.net and other dns checking tools are still showing the websites as not fully propagated, in addition my Vercel websites are still showing as pending and "Invalid Configuration" and my Zoho Mail console is further showing as the domain name configured and "MX Verification failure".
