What is the Subject Analyzer?

The subject analyzer checks the subject line of each message sent to your mailbox. It looks for certain words that are generally associated with spam in the subject line of the email. Also, it checks the header of a message to
see if a spammer has tried to manipulate the information contained there (such as the date, time, or mail
server name) to make the mail appear legitimate.

A message will receive a value based on how many spam criteria are detected and how many non-spam items are found. Based on this system, the messages which contain the highest level of spam criteria are most likely spam.
The level you select for the analyzer (off, low, middle, high) level will determine how many criteria must be met before a message is marked as spam.  Although medium is recommended, many people prefer to begin with low.

• Low - (recommended to start) This only filters out messages that contain many spam criteria. If you find too many spam messages reach your inbox, you can switch to medium.
• Medium - This filters out messages that contain a good amount of spam criteria.
• High - This filters out anything which meets the spam criteria. This may result in non-spam messages being marked incorrectly as spam.
