Domain Email DNS Checker
Read MX, SPF, DMARC, and DKIM names you provide. It is a configuration report, not a delivery guarantee.
Your result
Type a mail domain and press Look up to check its records.
How to use it
- Type the mail domain.
- Type DKIM selectors if you know them, separated by commas.
- Press Look up and read the last line.
Examples
- Selector presentexample.test, selector s1 MX: 10 mail.example.test SPF: v=spf1 -all DMARC: v=DMARC1; p=reject DKIM s1: present delivery: not tested
- No selectorexample.test, selectors blank MX: 10 mail.example.test SPF: v=spf1 -all DMARC: v=DMARC1; p=reject DKIM: no selector typed delivery: not tested
- Selector missingexample.test, selector s2 MX: 10 mail.example.test SPF: v=spf1 -all DMARC: v=DMARC1; p=reject DKIM s2: (none) delivery: not tested
Tool details and privacy
Type a domain and up to three DKIM selector names. This site reads MX, the SPF text record, DMARC, and those DKIM names. The last line says delivery was not tested.
The report shows which mail settings are published. It does not send a message and it does not prove that mail will arrive.
Options
- A blank selector list says no selector was typed.
- A DKIM key is not printed. The line says present or (none).
- The result is cached for about five minutes.
Limits
- This is a settings report, not a delivery test.
- DNS is read and is not changed.
- More than three selectors is refused.
Privacy
What you type is sent to this site so it can ask a public service or DNS. It is not stored in the tool analytics. A failed lookup is an error, not a made-up result.
