Why Email Authentication Matters

SPF and DKIM prevent spoofing and ensure your emails are delivered to the inbox rather than spam.

Configuring Records in cPanel

1. Access Email Deliverability

Go to Email > Email Deliverability in the cPanel interface.

2. Repair DNS Records

Click "Manage" next to your domain. If records are missing, click "Install Suggested Record".

# SPF Record Example
v=spf1 +a +mx +ip4:1.1.1.1 ~all
# DKIM
A digital signature for your mail headers.

Testing Your Setup

Use external tools to verify that your SPF and DKIM signatures are valid.

Success: Validated records improve your sender reputation significantly.
