Antispam
The antispam analysis function checks email for various characteristics of spam. If the email hybrid service is enabled and configured, it performs antispam analysis as well (Email Security Hybrid module is required). If email hybrid service is not configured or available, a combination of other on-premises tools is used for effective antispam analysis. Configure the antispam filter on the page
.The email hybrid service analyzes incoming email and blocks any message that it recognizes as spam. Mail that the hybrid service allows into the system for processing includes a header that contains an analysis result score. The email system uses this score to determine how to handle the message. If that score exceeds a specified spam threshold, the email system treats the message as spam and handles it according to applicable policy. In this case, the on-premises email security software does not perform its own, separate antispam analysis.
