domain Monitoring only DMARC p=noneMail by IONOS · Mail handled by mx00.ionos.co.uk, mx01.ionos.co.uk
Findings
-
Fail Could not talk SMTP to mx00.ionos.co.uk on port 25 SMTP-CONNECT-FAILED
ConnectionError: connection closed
How to fix: Check the server is listening on port 25 and not firewalled from the internet.
-
Fail Could not talk SMTP to mx01.ionos.co.uk on port 25 SMTP-CONNECT-FAILED
ConnectionError: connection closed
How to fix: Check the server is listening on port 25 and not firewalled from the internet.
-
Caution DMARC policy is p=none (monitor only) DMARC-P-NONE
Failing mail is still delivered. Fine while collecting reports; move to quarantine or reject once legitimate sources align.
How to fix: Set p=quarantine (with pct= to ramp), then p=reject.
-
Caution Spoofing protection: monitoring only SPOOF-PARTIAL
DMARC exists but does not enforce; forged mail is still delivered.
How to fix: Move DMARC to p=quarantine or p=reject.
-
Note No DKIM key found under common selectors DKIM-NOT-DISCOVERED
Selectors are chosen by the sender, so a key may exist under a name we did not try. Check a real message header for the s= tag.
-
Note No aggregate report address (rua) DMARC-NO-RUA
You receive no visibility of who sends as your domain.
-
Note No MTA-STS policy MTASTS-NONE
Optional; protects inbound mail against TLS downgrade.
-
Pass SPF uses 1 of 10 permitted DNS lookups SPF-LOOKUPS-OK
-
Pass SPF ends with ~all (soft fail) SPF-SOFTFAIL-ALL
Fine with DMARC enforcing; -all is stricter.

Selectors are chosen by the sending service, so a key can exist under a name not tried here. The s= tag in a real message header names it.

Open relay test owners only
Checks whether each mail server accepts mail for recipients at other domains, which spammers exploit. Because the test sends SMTP commands to your server, it is only offered to verified owners.
Create an account and verify the domain to run this test.
