Spam Deny List
By default, email addresses or domains that are added to your Spam Deny List will be automatically rejected for all Email Security users.
To see the entries currently in your Spam Deny List, visit your USS Dashboard and click Products ⟶ E-mail Security ⟶ Spam Deny List.
By default the Global safe list entries will be displayed. You can select a different mailbox or start typing the name of a mailbox to change the search scope.
Viewing Personal Deny Lists
Users can also maintain their own Personal Deny List. You can quickly view each user's Personal Deny List by selecting their email address from the drop-down list. The users themselves can manage this via the End User Portal.
