1. How does StarMaille determine which messages are spam?

StarMaille employs an extensive range of tests on incoming messages to detect spam. These include traditional, widely used approaches for spam detection such as message authenticity checks, header analysis, message signature analysis, an artificial intelligence Bayesian engine, databases of domain names and addresses used by spammers, and whitelists and blacklists. StarMaille has also developed advanced, industry-leading techniques such as real-time message source analysis, graphics analysis, and user-based message profiling.

2. What happens to messages that are detected as spam?

You have several options for handling the spam messages detected by StarMaille. Junk messages can be 1) redirected to a StarMaille-hosted quarantine, 2) redirected to an alternative email address such as This e-mail address is being protected from spambots. You need JavaScript enabled to view it , 3) identified as spam in the subject line and delivered to the intended recipient, or 4) deleted. These options can be configured company-wide or on a per-user basis, and can be changed at any time.

3. What percentage of junk email does StarMaille catch?

The detection rate varies by customer and is based on the email traffic patterns for a given domain, and on StarMaille's aggressiveness for that domain (customers can configure how aggressive the filter should be). On average, StarMaille blocks over 98% of junk email and 100% of email-borne viruses.

4. What are whitelists and blacklists?

Whitelists are rules that allow messages to be delivered based on their 'from' email address or domain name, regardless of content. If you would like to guarantee that all messages from yourcustomer.com, for example, will not be flagged as spam regardless of what those messages contain, you can simply add that domain to your whitelist. Conversely, blacklists are rules that block messages based on the domain name or email address of the sender.
