Email DNS Checker (SPF, DKIM, DMARC, MX)
Look up a domain's MX, SPF, DMARC and DKIM (with selector) records via DNS over HTTPS and flag common mistakes. Queries go directly from your browser.
FAQ
Where are queries sent?
Directly from your browser to the DNS-over-HTTPS service you choose (Cloudflare or Google). They do not go through MOKLAV servers.
I don't know my DKIM selector
Selectors cannot be listed from DNS. Use the s= value from the DKIM-Signature header of an email you sent.
Can it check blacklists or SSL?
No. It checks only MX, SPF, DMARC and DKIM DNS records.
