SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.mountainscholar.org TXT "v=DMARC1; p=none; rua=mailto:dmarc@mountainscholar.org"`, review the reports, then move to p=quarantine and p=reject.

CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.
asset: https://mountainscholar.org/
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.
asset: https://mountainscholar.org/
Nothing tells receiving mail servers which hosts may send as @mountainscholar.org, so anyone can. Even a domain that sends no mail should say so, or it becomes a free spoofing target.
What to do
Publish `v=spf1 -all` to state that this domain sends no mail.
asset: mountainscholar.org
Full URLs — including any tokens or IDs in them — are sent to every third party the page links to.
What to do
Send `Referrer-Policy: strict-origin-when-cross-origin`.
asset: https://mountainscholar.org/
Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: mountainscholar.org
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
