What is the check box next to each email address in my Safe/Blocked Senders List?
A This does not indicate whether an email address in your Safe or Blocked Senders List is active. It is used to select email addresses in order to edit or delete entries from your list. If you want to edit an email address, check the check box next to the email address and select Edit in the menu bar at the top. You will then be able to edit the selected email address. If you want to delete a single or multiple email addresses, check the check box next to the email addresses you want to delete and select Delete in the menu bar at the top of the window. All the entries that were selected are then deleted.
