Findings

mx

No MX records. Mail sent to this domain has no defined destination.

Fix: Publish MX records pointing at your mail host.
dkim

The zone answers for every name under _domainkey, so we cannot tell which DKIM selectors are real. A wildcard here also lets anyone claim a selector on this domain.
```
mailgrade-wildcard-sentinel._domainkey.gov.uk answers
```
Fix: Remove the wildcard record covering _domainkey and publish only the selectors your mail provider issued.
spf

SPF is published and enforcing.
```
v=spf1 -all
```

dmarc

DMARC is enforcing with p=reject.
