This interface allows you to enable or disable Greylisting for each domain on your account. Greylisting defends email users against spam. When you enable Greylisting, the mail server will temporarily reject any email from a sender that the server does not recognize. If the email is legitimate, the server that sent it will try to send the email again after a delay. After a sufficient amount of time, the server will accept the email.
