Findings

spf

SPF has no enforcing terminator, so unauthorised senders are neither marked nor rejected.
```
v=spf1 redirect=_spf.fb.com
```
Fix: End the record with -all.
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.
mta sts

No MTA-STS policy, so inbound mail can be downgraded to an unencrypted connection.

Fix: Publish _mta-sts.meta.com and host a policy at https://mta-sts.meta.com/.well-known/mta-sts.txt.

Mail is handled by Proofpoint.
