Spam Filters  

There are many definitions of spam, but one of the most useful ones is the following:  

"Spam: unsolicited email, usually of a commercial nature." 

Spam is the electronic version of junk mail, and has been around since the Internet was 

created. Spam filters are a way of filtering your email to remove unwanted mail based on a 

variety of criteria. You can block any sort of email, not just mail of a commercial nature. Blocked 

mail is deleted automatically   it does not even bounce back to the sender. These filters are 

quite flexible   some examples are provided after the instruction on how to add a spam filter 

below. All filters are cumulative.
