Some e-mail servers have built-in spam filters that scan incoming e-mail. These server-side spam filters can optionally tag the subject line of incoming messages as spam. For example, if a server-side spam filter finds that an incoming message is spam, it can add the server tag "***SPAM***" to the subject line of the message before delivering the message to your BlackBerry.
Antair Spam Filter can take advantage of these server tags. If your e-mail server tags incoming spam messages, you can enter this tag into the server tag section of Antair Spam Filter, and Antair Spam Filter will, in turn, treat all tagged messages as spam.
