DKIM signing key published
SPF, DMARC, DKIM, MTA-STS: protection against spoofed mail in your name.
Why it matters
Unsigned mail is easier to forge and more likely to be filtered as spam; DMARC then depends on SPF alone, which breaks on forwarding.
How to fix it
Quick fix · under 1 hour- Enable DKIM signing in your mail provider's admin console.
- Publish the TXT record it gives you, then turn signing on.
- If you already sign with a custom selector, you can ignore this item.
