What is the process to report a false positive in Mimecast?

Reporting a false positive in Mimecast involves using the Provisioning Address Book (PAB) to indicate that a filtered email was incorrectly marked as a threat. This process is essential because it helps Mimecast improve its filtering algorithms and ensure that legitimate emails are not wrongly categorized. By submitting feedback through the PAB, users provide specific information about the email in question, allowing the Mimecast system to learn from these incidents and adjust its threat evaluation procedures accordingly.

Using the PAB is a direct and efficient method for users to communicate with Mimecast about their experiences with email filtering, making it a preferred choice for reporting false positives.

Other options, while they may seem plausible—such as contacting customer support directly, changing email settings, or submitting a feedback form through the website—do not provide the targeted approach that the PAB offers for specifically addressing false positives in the filtering system.
