E-mail messages from people on the Safe Senders List or to people on the Safe Recipients List will automatically be allowed into your Inbox. E-mail messages from people on the Blocked Senders List will be blocked from your Inbox and sent to the Junk E-mail folder.
Messages from or to people on your Safe lists are always allowed into your Inbox. And, logically enough, messages from people on your Blocked Senders List are banished to the Junk E-mail folder.
Note By default, messages from e-mail addresses in your Outlook Contacts folder are considered safe and allowed into your Inbox automatically. Similarly, if you work at a company using Exchange Server, you'll automatically receive messages from people within your organization.
Wondering what happens if a name is on both a Safe list and a Blocked list? The Safe list wins! If a name is on one of your Safe lists, messages from that person will always be delivered to your Inbox.
