Findings

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.qq.com and host a policy at https://mta-sts.qq.com/.well-known/mta-sts.txt.
