Spam Filtering

Untangle's free Spam Blocker uses SpamAssasin , one of the most trusted and reliable spam filters for identifying and filtering spam.

How Spam Blocker works:

It uses a wide range of heuristic tests on mail headers and body text to identify "spam", also known as unsolicited commercial email.

Once identified, the mail is then tagged as spam for later filtering using the settings that are specified within Untangle.

• Point and Click Install
• Installs Transparently
• Requires no changes to your email configuration
• No time spent on the command-line, researching settings etc.,

SpamAssassin typically differentiates successfully between spam and non-spam in between 95% and 100% of cases, depending on what kind of mail you get and your training of its Bayesian filter.

Specifically, SpamAssassin has been shown to produce around 1.5% false negatives (spam that was missed) and around 0.06% false positives (ham incorrectly marked as spam).
