You can choose what type of scan should be performed on messages received from authenticated sources or local servers. Scanning of such messages is recommended as it increases protection, but necessary if you are using the built-in Microsoft SBS POP3 Connector to fetch email messages from external POP3 servers or mail services (for example Gmail.com, Outlook.com, Yahoo.com, gmx.dem, etc.). For more information see POP3 Connector and Antispam.
Choose level of protection from the drop-down menu. We recommend that you use Antivirus protection (default setting), especially for internal connections as it is unlikely that phishing or spam messages will be distributed via your local servers. However, you can increase the protection for Microsoft SBS POP3 Connector by choosing Antivirus and anti-phishing protection or even Antivirus, anti-phishing and antispam protection.

When enabled, scan results are written into message headers. These message headers start with X_ESET making them easy to recognize (for example X_EsetResult or X_ESET_Antispam).
