Another important feature of Alligate server is Kill & Black Lists. If you wish to use this feature then refer the below steps:

1. Open the "Alligate SMTP Gateway Control Panel". (Start -> All Programs -> Alligate)

2. From the selection menu click on “Kill/Blacklists” option and set the settings as per your requirement.
