Scanners process inbound and outbound messages and route messages for delivery. Scanners download virus definitions, spam signatures, and other security updates from Symantec Security Response. Scanners run filters, render verdicts, and apply actions to messages in accordance with the appropriate policies and settings. You can configure Scanners to limit the number of connections, which can help reduce the number of messages to be scanned.

You must have Full Administration rights or Manage Settings view rights to create, modify, enable, disable, or delete Scanners.
