black list of email addresses suspected of sending spam
Black list is a list that is not connected with anything good – it contains a names of servers or email addresses that may be sending spam messages. And what is more, it helps to protect out email boxes against them. Thanks to them our spam filters are more sensitive and catch almost everything even slightly connected with the name from the black list. Nobody likes receiving spam messages because they only rubbish our email boxes and takes our free place which can be used in different way. They carry the content which not necessarily interests us. And what is probably the most important – we did not gave our permission for receiving such messages. And this is the main difference between spam messages and for example mass or bulk emails – those second ones are sent only after the time when client show his will to receive additional information by subscribing to a special list of recipients. Black list is created to prevent such activity without any surveillance or permission.
