Domain check: MX, SPF, DMARC and DNS
Free domain check: verify MX, SPF, DMARC and DKIM and look up DNS records – with clearly explained errors. No data is stored.
Background
What is checked.
// 01
MX
Shows which servers accept e-mail for the domain. If it is missing or wrong, no e-mail arrives.
// 02
SPF
List of servers allowed to send on behalf of the domain. Protects against spoofed senders and improves deliverability.
// 03
DMARC
Defines what happens to e-mail that fails SPF and DKIM – monitor, move to spam or reject.
// 04
DKIM
Digital signature of outgoing e-mail. The public key is stored in the domain’s DNS.
Errors found?
Setting up SPF, DKIM and DMARC correctly protects against spoofed e-mail in the company’s name and makes sure e-mail is reliably delivered.
