What does the term "Spam Detection Level" refer to in Mimecast?

The term "Spam Detection Level" in Mimecast refers to the sensitivity level at which spam is identified. This concept is crucial for effectively filtering out unwanted emails while ensuring legitimate messages are not mistakenly categorized as spam. The sensitivity determines how aggressive the system will be in detecting and blocking potential spam.

A higher sensitivity level might result in more aggressive filtering, potentially catching a broader range of unwanted emails but could also lead to some false positives, where legitimate emails are misclassified as spam. Conversely, a lower sensitivity level will allow more emails through, but it risks letting some spam reach the inbox. Properly configuring the spam detection level helps organizations balance security needs with the necessity of smooth email communication.

Understanding the sensitivity level is essential for users and administrators looking to optimize their email gateway's performance, ensuring that the system aligns with the organization's specific requirements for spam protection.
