How Does TSPs Junk Mail Filter Work?
Every email that goes through our system from another mail server is rated on it’s “spamminess” based on dozens of criteria. When it matches any of these criteria, it gets points for each one. Once the number of points go above a set threshold – your “Spam Threshold” – our spam filter automatically moves the spam into your Junkmail folder on the server. This threshold is set to 5.1 by default. By lowering this number, you can increase the number of spams caught by your individual filter. However, this also increases the chance that a legitimate email may be caught by the filter. For most people the default is sufficient, but if you’d like your spam filter to be more aggressive, you can lower this score. We recommend lowering the score by no more than 0.3 at a time. If the threshold is lowered more than 4.0, there is a very high likelihood that legitimate emails will be caught by the filter.
