SPF (Sender Policy Framework) prevents email spoofing and improves deliverability.
Recommended SPF Record:
```
v=spf1 include:_spf.adaptivewebhosting.com ~all
```
To Add in Plesk:
1. Go to Websites & Domains > DNS Settings
2. Add a new TXT record
3. Leave the name blank (or @)
4. Enter the SPF value above
5. Save changes
Verify Your SPF:
Use mxtoolbox.com/spf.aspx to verify your SPF record is correct.
Important:
- Only one SPF record per domain
- If using multiple email services, combine them:
v=spf1 include:_spf.adaptivewebhosting.com include:_spf.google.com ~all
