Spam Control at CCRMA
Welcome to CCRMA's Spam fighter homepage.
Having a 'Spam Free' inbox is a requires vigilence on everyone's part. In the text below, we'll describe what you can do to minimize your Spam.
First you need to determine which email client you will be using (e.g. Evolution, Thunderbird, WebMail, or Pine). Spam fighting is much more difficult if you use more than one email client. The descriptions below are for exclusive use of only one client. These solutions also assume that you will not be using client side 'intelligent email filtering' (where the your email client 'learns' about Junk mail).
Filtering is done through a program called
This file is key in your Spam control effort. It is a hidden or 'dot' file, that you should create (for newer accounts it will have been created for you) in your home directory with the following contents, at a minimum:
# directory where mailboxes are located # this is the default used by pine MAILDIR=$HOME # pipe the message through spamassassin in cm-home :0fw | spamc -d 188.8.131.52
SpamAssassin will run each email through its filter (filter rules are updated frequently to reflect new spam 'threats'). SpamAssassin adds several lines to your email header's. When viewing your email in your email client, you normally only see an abbreviated header which shows the 'From:', 'To:', 'Date:' and 'Subject:' lines, but you can select elect to see the full headers as well. The lines added by SpamAssassin to your (normally hidden) email header include:
X-Spam-Level: X-Spam-Checker-Version: X-Spam-Status: X-Spam-Report:
For now, let's look at
X-Spam-Level since it is on this line, that you will create filter's in your email client. If you take a look at the header you'll see one line that looks like this:
X-Spam-Level display's Spam Level using the asterisk. Here, or example, for 'Spam Level 5' with 5 asterisks.
The idea then, is to establish email filter's, filtering on the asterisk, in your email client which, directing these messages into more manageable folder's or to delete the message automatically (wise for Spam Level 5).
