Check a domain

No login required

The domain name is sent to Elonsh AB’s server for queries against public DNS and the domain’s HTTPS server. The result is temporarily kept in server memory for no more than five minutes.

What the result helps you see

Incorrect DNS and email settings can cause downtime, delivery problems, and make it easier to spoof email from a company domain. The check shows what was found and provides a practical recommendation where something can be improved.

The check includes

MX
SPF
DKIM
DMARC
DNSSEC
CAA
TLS/SSL
HTTP headers
