How to fix SPF record errors for cPanel email

Repair SPF failures that affect outbound delivery and authentication.

SPF errors happen when the domain's TXT record does not authorize the server that is sending mail for the domain, or when multiple SPF records exist.

Common symptoms

  • Recipients report SPF fail or softfail
  • Mail lands in spam unexpectedly
  • DNS tools say the domain has more than one SPF record

Troubleshooting steps

  1. Find all current SPF TXT records for the domain and remove duplicates so only one SPF policy remains.
  2. If your domain sends from the cPanel server, ensure the SPF record includes the server or the provider's recommended mechanism.
  3. If you also use third-party senders such as marketing platforms or Google Workspace, add their required includes carefully.
  4. Avoid exceeding SPF lookup limits by removing obsolete includes and flattening complexity where possible.
  5. After updating DNS, retest delivery and allow time for propagation.

Additional notes

  • A domain must publish one combined SPF policy, not multiple separate SPF records.
  • SPF alone does not guarantee inbox placement; DKIM and domain reputation still matter.

When to contact support

Contact support if you are unsure which services currently send mail for the domain.
