Maintain Your Spam Folder
It is up to you to decide whether to delete or keep the mail filed in your spam folder. Spam is not normally highlighted as being "unwanted" mail. The Andrew Spam Filter has identified common aspects of spam and used this information to develop its rules. Because legitimate email can sometimes be mistaken as spam, you should review the mail in your spam folder before deleting it. You should also regularly clean out your INBOX.spam folder to avoid filling your mail quota.
If you find that spam from a particular source is not being filtered, or that legitimate mail is inaccurately being filtered, customize your Accept list or Filter list to accommodate these domains or email addresses.
