DomainKeys Result - DNS Unreachable

The DomainKeys Verification Category of DNS Unreachable page allows you to choose an action when the DomainKeys Verification filter is enabled.  

This action activates when the message has an unreachable DNS.

Important: After updating verification settings be sure to restart your SMTP and Queue Manager services.

The action to be taken when the query result is met

• Action. Select one of the following actions:
  • None. No action is performed.
  • Delete. Immediately deletes the message.
  • Forward to Address. Forwards the message to a specified e-mail address. Enter an e-mail address in the text box to the right of this option.
  • Insert X- Header (default). Inserts an X-Header into the message indicating that the message was identified with Invalid Signature for DomainKeys.
  • Move to Mailbox. Moves the message to the user's mailbox specified in the text box to the right of this option. If the mailbox does not exist, it is created.

    Tip: We recommend that you select the Insert X-Header option instead of Delete until you know that the DomainKeys options are setup to best suit your filtering requirements.

  • Reject Connection. Immediately ends the message connection, and message will not be accepted.
• Prefix subject with. If you want to add a custom prefix subject to messages that are identified as DomainKeys failure, select the Prefix subject with check box (cleared by default). The default subject prefix is entered in the text box to the right and is based on the DomainKeys failure. You can also enter a custom message in this box.
