Findings

mx redundancy

Only one mail exchanger is published, so there is no failover.
```
smtp.google.com
```
Fix: Add a secondary MX at a higher priority number.
spf

SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.
```
v=spf1 include:_spf.google.com ~all
```
Fix: Move to -all once you have confirmed all senders are listed.
dkim

No DKIM key found at any common selector. Either DKIM is not configured, or it uses a custom selector we cannot discover from DNS alone.

Fix: Enable DKIM signing at your mail provider and publish the selector they give you.
mx

Mail is handled by Google Workspace.
```
10 smtp.google.com
```
