Fix “Email failed SPF validation”

Ask your email administrator to check the settings that verify your sending email service.

If you receive “Email failed SPF validation,” WestFax couldn’t verify that the email server sending your message is authorized to send for your domain.

SPF, short for Sender Policy Framework, is a setting your organization publishes for its email domain. It lists the servers allowed to send email on the domain’s behalf. WestFax requires SPF validation for Email to Fax to help protect against forged sender addresses.

What to do next

  1. Share the error with your email or domain administrator.
  2. Ask them to check that your domain has an SPF record and that it authorizes the email service used to send your fax.
  3. If they make a change, allow time for it to take effect, then try sending again. Some updates may take effect in 15–30 minutes, but the timing can vary.

Setup resources for your administrator

If you use another email provider, ask that provider for its SPF instructions. For additional background and resources, see SPF and Email to Fax: Why SPF is required.

Your administrator should review the existing SPF record before making changes so your other authorized email services remain included.

If the error continues after your administrator reviews the settings, share the error message, sending email address, and what’s already been checked with us. We’re happy to help you work through the next step.
