How to set a score?
You can set a score based on which the tool will filter new messages. The score can be between 1 and 10. The higher the value you set, the fewer messages will be filtered and viceversa. If you are not familiar with spam scores, we recommend you to leave it at this value.
Also, you can set SpamAssassin to automatically delete messages that have the determined score.
IMPORTANT: Sometimes the tool might flag valid messages as spam. The auto delete option might delete some of those valid emails.You can also use SpamAssassin to block certain email addresses, to do that, type in a certain email address email@example.com or all emails coming from a particular domain, by entering *.domain.com.
You can also whitelist emails, if you want them to pass the SpamAssassin.
