Configuring Spam Preferences - Spam Controls
The Spam Preferences Control Panel lets you:
Here's a snapshot of the Spam Preferences Control Panel
The spam filter gives each email a spam score. The higher the score the more likely an email is spam. The Filter Sensitivity sets the threshold score over which an email will be considered spam. A setting at the far right is 1.0 and at the far left is 10.0. A setting of 5.0 is a good starting point.
When an email is identified as spam, the filter produces a report showing the tests performed and the spam scoring for each test. This report and the original email can be combined in different ways. You can try the different selections but the Default is a good choice.
The spam filter will add headers to your email. These headers identify the spam filter, provide the spam score and indicate whether the email has been determined to be spam. You can control what is added to your email headers with this panel. We think the settings shown below are pretty good.
Email Subject Rewriting
If an email is determined to be spam the filter can add some text to the email's subject line. This makes it easy to see at a glance that an email is spam. This panel controls whether any subject rewriting will be done and, if so, what test will be prepended.
This panel allows you to select the languages in which you expect to receive legitimate email. Email is any other language will be considered possible spam. Control-click to accept multiple languages.
You can click on the links in this panel to find out more about these spam databases. The two selections show below offer a good combination of accuracy and network look-up speed.
Save Your Spam Preferences
Make sure you click on 'Apply' to save your spam preferences.
A separate section allows you to create whitelist and blacklist rules. There are three types of rules:
For the three types of rules you may enter complete email addresses or use wildcard formats to encompass all addresses within a email@example.com applies to every address at the domain "spamisp.com"
*@*.spamisp.com applies to every address at any sub-domain of "spamisp.com"
Close the Spam Preferences Control panel window when you are done.
