    • Envelope Sender - not the same as the 'from.' This is typically used on mailing lists.
    • 'From' Header - this is what you see on the from line in the message header
    • Recipient - this is who the message is sent to. 
  2. Pending the action you chose, it will open the Sender List page and add to the proper list.

If the email has been Quarantined it is possible to:

  1. Allow this address.
  2. Allow this domain


If the email address has been delivered, it is possible to:

  • Block this address
  • Block this domain
