How to set up email authentication (SPF, DKIM, DMARC)

Email Authentication: SPF, DKIM, DMARC

Email authentication helps ensure your emails are delivered and not marked as spam.

SPF (Sender Policy Framework):

Tells receivers which servers are allowed to send email for your domain.

1. Log in to cPanel
2. Go to Email > Email Deliverability
3. Click Manage next to your domain
4. Enable SPF or add a custom TXT record
5. Standard SPF record: v=spf1 a mx include:yourdomain.com ~all

DKIM (DomainKeys Identified Mail):

Adds a digital signature to your emails so receivers can verify they came from you.

1. In Email Deliverability, enable DKIM
2. The DNS record will be added automatically

DMARC (Domain-based Message Authentication):

Tells receivers what to do if SPF or DKIM checks fail.

1. Add a TXT record with name _dmarc.yourdomain.com
2. Start with monitoring mode: v=DMARC1; p=none; rua=mailto:you@yourdomain.com
3. Once satisfied, switch to p=quarantine or p=reject
