On the Options tab, select the level of protection that you want.
No Automatic Filtering Although this turns off the automatic Junk Email Filter, messages are still evaluated by using the domain names and email addresses in your Blocked Senders List.
NOTE: If you want to turn off the Junk Email Filter, you must also remove names from the Junk Email Filter lists.
Low If you don't receive many junk messages, or want to filter only the messages that are the most obvious junk, select this option.
High If you receive lots of junk messages, but don’t want to restrict messages from senders on your safe lists, select this option. You should periodically review messages moved to the Junk Email folder, because some legitimate messages might also be moved.
Safe Lists Only This is the most restrictive option. Any message that is sent neither from someone on your Safe Senders List nor to a mailing list on your Safe Recipients List, is classified as junk.
