There are a number of spam filters and 'Spam Lists' that an email message must pass through before making it to your mailbox--this is the built-in system we have in place that prevents a large majority of spam email from getting through. Depending on what these various filters determine, a 'weight' is assigned to a message depending on how likely it is to be spam. If a particular message is unlikely to be spam, the filters and spam lists will cumulatively assigned it a low (or no) weight. On the other hand, a high weight is assigned to a message with a high likelihood of being unwanted spam.
