SpamAssassin is an automated email filtering system that attempts to identify spam messages based on the content of the email's headers and body.

 

Features

 

  • Wide-spectrum: SpamAssassin uses a wide variety of local and network tests to identify spam signatures. This makes it harder for spammers to identify one aspect which they can craft their messages to work around.
  • Free software: it is distributed under the same terms and conditions as other popular open-source software packages such as the Apache web server.
  • Easy to extend: Anti-spam tests and configuration are stored in plain text, making it easy to configure and add new rules.
  • Flexible: SpamAssassin encapsulates its logic in a well-designed, abstract API so it can be integrated anywhere in the email stream. The Mail::SpamAssassin classes can be used on a wide variety of email systems including procmail, sendmail, Postfix, qmail, and many others.
  • Easy Configuration: SpamAssassin requires very little configuration; you do not need to continually update it with details of your mail accounts, mailing list memberships, etc. Once classified, site and user-specific policies can then be applied against spam. Policies can be applied on both mail servers and later using the user's own mail user-agent application.
 
BoxTrapper

It is highly recommended that you use spamassasin in conjunction with boxtrapper as it will reduce loads on the server and reduce backscatter to illegitimate email addresses

Configuring the boxtrapper

 

Overview

The cPanel BoxTrapper configuration allows you to set what email addresses are associated with the BoxTrapper and also how long logs and queue messages are kept for those accounts.

 

 

Steps

1 To access the Mail Menu, click on the  icon above the word Mail on the main screen of your cPanel interface.

2 Click on BoxTrapper Spam Trap.

3 To enter the BoxTrapper menu, click on the word Manage.

4 Click on the words Configure Settings.

5 Change the settings to what you need:

 

Email addresses going to this account:

Place all of the email addresses that you wish to have the BoxTrapper enabled on in the field next to this option. These addresses should be separated by commas.

How many days logs and messages in the queue should be kept:

Place a number in the field next to this option that corresponds with the number of days you wish to keep mail logs and mail messages in the queue. (Setting this higher will use up more disk space)
