Using the Filter Side Bar
To view the Filters sidebar, either click View > sidebar or use the shortcut keys of [Ctrl] + [F7].
This section of the main work area comprises of two tabs, Lists and Evaluation
The Lists section is comprised of
The Friends List contains the email addresses of people whom you always want to receive mail from. While other spam tools are used to evaluate the email even when it is termed as a friend, it is given more weight as a legitimate email.
The Blacklist gives you an easy way to banish spammers from your inbox. Once an address is added to your Blacklist, the next time you receive an email from that address, it is automatically marked for deletion (unless the content of the email is good). The Blacklist is an effective tool against email from mailing lists that you may have unwittingly signed up for (or been submitted to) and from companies who take no notice of your unsubscribe requests.
Filters allow you to define what MailWasher tags as spam like email or legitimate email. You can specify certain words or combinations of words or use Regular Expression filters that automatically trigger a categorization from MailWasher.
The Evaluation section lists all the spam tools used in the evaluation of the email and a score for each. These individual scores are used to make a total score. This total score indicates if the email is spam, good or undetermined.
