Set up SPF, DKIM, or DMARC records for my hosting email
This article will show you how to set up SPF, DKIM and DMARC records within your Virtual Private Server.
If you send emails using a custom domain name, you may need to include the following records on your associated domain: Sender Policy Framework (SPF), Domain Keys Identified Mail (DKIM) and Domain-based Message Authentication, Reporting and Conformance (DMARC).
To add an SPF (Sender Policy Framework) record, simply add a TXT record that includes the following:
v=spf1 include:secureserver.net -all
If your VPS uses cPanel, please check the following page for details on how to add a DKIM record: Email Deliverability in cPanel
