What is Apache SpamAssassin™

Apache SpamAssassin is an open-source tool developed to filter and classify emails while blocking spam. It uses a combination of subject line and body text analysis, Bayesian filtering, and DNS blacklists, to drastically limit and can even prevent spam from reaching your inbox.

In the “Rules” section, select “Spam Bar” from the first dropdown, and “Contains” from the second dropdown.

In the next field enter a spam score using a series of (+) symbols, with 5 being an adequate score for an individual user.

Rules field

Next, under the “Actions” section, set the dropdown to “Deliver to Folder”, and set the name of the folder to “spam”.

Actions field

Remember: Be sure to check your “spam” folder regularly to make sure that real mails are NOT being marked as spam incorrectly. It is also a good idea to empty your spam folder regularly to save disk space on your mail server.
