How to Control Spam

Citadel Network has a full arsenal of tools to protect you from spam and gives you individual controls to customize your spam protection. These individual controls exist both on our server as well as in your email software. You can access these controls by logging into your email through our website.

SpamAssassin is an intelligent spam filtering package that runs on the mail server to perform numerous tests on each message. It adds up the results of each of those tests to give each message a total score. The higher the score, the more likely it is to be spam.

You can control what happens to messages that might be spam by setting your personal Tag Level and Quarantine Level. Any message sent to you that scores above the Quarantine Level is delivered to a special quarantine folder on the server, and you never have to see it. Any message sent to you that scores above the Tag Level, but below the Quarantine Level, has it's subject modified to add "***SPAM***". This allows you to see at a glance which messages are likely to be spam, but not likely enough to discard automatically.

You can also override the scoring to allow messages from individuals by adding their email addresses to your personal Whitelist. Users on your personal Whitelist are allowed to send mail to you regardless of the spam score. You can also block specific individuals by adding them to your personal Blacklist.

Client Side Filtering

You can use the website for all your email functions, but if you have chosen to use email client software installed on your computer, there are some additional things you may want to configure in that software.

Some email client software can take spam tagged by the server and automatically file it in a selected folder when it is downloaded to your computer. This keeps likely spam separate from your other mail.
