DMARC (Domain-based Message Authentication) helps protect your domain from email spoofing.
Basic DMARC Record:
```
v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com
```
To Add in Plesk:
1. Go to DNS Settings for your domain
2. Add a TXT record
3. Name: _dmarc
4. Value: v=DMARC1; p=none; rua=mailto:your@email.com
DMARC Policies:
- p=none: Monitor only (start here)
- p=quarantine: Send suspicious to spam
- p=reject: Block suspicious emails
Recommended Approach:
1. Start with p=none to monitor
2. Review DMARC reports
3. Gradually move to quarantine, then reject
Ensure SPF and DKIM are configured before enabling strict DMARC policies.
