Rule Config: SPF

Sender Policy Framework (SPF) is a technique based on a special DNS record to identify valid mail senders. Here, you can select the options that affect an SPF policy rule.

  1. Select which SPF results you want as a condition of your rule.
  2. Select one or more of the following check boxes:
    • None: The domain does not have an SPF record.
    • Pass: The SPF record designates the host to be allowed to send.
    • Fail: The SPF record has designated the host as NOT being allowed to send.
    • SoftFail: The SPF record has designated the host as NOT being allowed to send, but is in transition.
    • Error: A syntax or evaluation error has occurred.
  3. Select Next.
