What built-in features assists Exchange in controlling spam?

The built-in features that assist Exchange in controlling spam include content filtering and connection filtering.

Content filtering works by analyzing incoming messages for specific characteristics or patterns that are commonly associated with spam, such as certain keywords or phrases. It can be configured to reject messages that match these criteria or to mark them as potential spam for further review. This feature significantly enhances the ability to identify and handle unwanted emails before they reach users’ inboxes.

Connection filtering, on the other hand, helps control which external domains or IP addresses can send mail to the Exchange server. It uses sender reputation and block lists to prevent messages from known spam sources from reaching the organization. By establishing rules around incoming connections, Exchange can effectively minimize the volume of spam that penetrates its defenses.

Together, these features provide a robust framework for managing and mitigating spam, ensuring that users receive relevant and legitimate communications while reducing the chances of encountering unwanted content.
