To remove a sender, click it in the list, and then click Delete.
To automatically add senders to the Approved
Senders list when you mark an email message as Not
Spam, select the check box on the bottom of the screen.
When your administrator has prevented "auto
add" Approved Senders behavior and you try to reprocess
a message, the original settings you specify are applied (if they
exist), and the check box for the "auto add" Approved
Senders feature is disabled.
Click Save.
Note
The email address can include an asterisk wild card
character.
