SPF or Sender Policy Framework is a standard to authenticate the sender domain of the email messages to reduce spam.
DKIM or DomainKeys Identified Mail is an authentication standard using a cryptographic signature of the sending domain for reliable and effective protection against spam.
The system automatically activates DKIM and SPF records for all new accounts. To activate or modify them manually on your cPanel account, follow the instructions below:
1. Go to cPanel > EMAIL then click on Email Deliverability.
2. Click on MANAGE.
3. Click on "INSTALL THE SUGGESTED RECORD" to activate the desired record:
- For DKIM record
- For SPF record
The corresponding "TXT" records are automatically added to your DNS zone file. You can check them from cPanel > DOMAINS > Zone Editor.
