To apply individual scanning settings to a mailbox:
Note: Here you can also specify what to do about the following categories of messages: messages from which malicious code was removed by Kaspersky Antivirus (Cured row); messages suspected of being infected with an unknown virus (Suspicious row); messages that contain corrupted files (Corrupted row); messages that contain code that resembles a known virus (Warning row); messages that could not be scanned because antivirus service was stopped or failed due to an internal error (Error row); messages that contained password-protected files (Protected row).
Now antivirus scans all mail coming to and from this mailbox in accordance with the settings you defined.
