Whitelisting and blacklisting email from certain addresses or domains
If you want to block email from certain addresses or domains, and if your administrator has enabled this feature, you can add them to your personal blacklist. Click Manage White/Black Lists on the message report that is emailed to you. You can also configure the report to always accept mail from certain addresses or domains. This is called your whitelist.
When you click Manage White/Black Lists, a search screen appears. If you have already added a list of email addresses or domains to your blacklist and whitelist, use this screen to select which email addresses and domains to display in your list. (Use it to filter the view of your list so you can modify the appropriate records more quickly.)
If you want to create a new list or add a new email address or domain to an existing list, click Click here to add new entries to your White/Black list. (See Adding new records for more details.)
