To Block or Allow emails please follow the guide. Some information on what each option does is seen below.

Safe Senders list: Email addresses and domain names in the Safe Senders List are never treated as junk email, regardless of the content of the message. You can add your Contacts and other correspondents to this list. All names and addresses in the Roehampton global address list (GAL) are automatically considered safe. The Safe Sender limit is 1024.
Safe Recipients list: If you belong to a mailing list or a distribution list, you can add the list sender to the Safe Recipients List. Messages sent to these email addresses or domain names are never treated as junk, regardless of the content of the message.
Blocked Senders list: You can easily block messages from particular senders by adding their email addresses or domain names to the Blocked Senders List. When you add a name or email address to this list, Outlook moves any incoming message from that source to the Junk Email folder. Messages from people or domain names that appear in this list are always classified as junk, regardless of the content of the message.
