Configuring Sender Policy Framework (SPF)

How to get here

The Sender Policy Framework (SPF) page provides administrators increased capability to stop incoming email from forged (spoofed) email addresses. Use the SPF settings to configure how to process email that is identified as forged email. Settings on the SPF page apply to the selected domain.

• Enable SPF. Select this checkbox to enable the SPF filter for the current host.  Default actions are specified to take for each SPF query result. You can, however, change the defaults by clicking the hyperlink under the SPF result. An Action to be Taken page appears, with the options for that action listed in a list box.
• SPF Result. This column lists all possible SPF results possible for this domain.
  • Fail
  • Softfail
  • Error
  • Temp Error
  • Neutral
  • None
  • Pass
• Action to be taken. This column lists the action chosen for each corresponding query result.
• Target. This column lists the mailbox or email address for a Move to or Forward to action, respectively.
• Prefix Subject. (Yes/No) This column lists whether or not the message will have an SPF Result prefix added to the message.
• With. This column lists the actual prefix, if chosen, for the corresponding query result.

Advanced Options:

• DNS Timeout (in seconds). Sets the total amount of time between DNS record checks (lookups).
• Maximum number of redirects. Sets the maximum number of redirects allowed when an SPF policy is queried and evaluated.
• Save. Click the button to save your changes. An "Update Successful" message and the time of the update appear.
