Set up SPF, DKIM, or DMARC records for my hosting email

If your email is using your company’s domain name, you may need to set up email authentication, which includes Sender Policy Framework (SPF), Domain Keys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC).

v=spf1 include:secureserver.net -all
