SPF, DKIM, DMARC (Beginner)
> These DNS records help other mail servers trust that your emails are really from you.
What This Is (In Simple Terms)
- **SPF**: tells which servers are allowed to send email for your domain.
- **DKIM**: adds a signature so emails can be verified.
- **DMARC**: tells receivers what to do if SPF/DKIM fail.
Why This Is Important
Without these, your emails may go to spam or be spoofed by attackers.
Getting Started
1. Identify where you send email from (Plesk server, Google, Microsoft, etc.).
2. Add the provided TXT records to DNS.
3. Success looks like: mail tests show SPF/DKIM/DMARC passing.
Common Mistakes to Avoid
- Having multiple SPF records (you should have one SPF record per domain).
- Setting DMARC too strict before testing.
