# Policies Tab

The Policies tab enables you to specify how your network should respond to messages classifications. In the On-session message blocking policy section, check which classifications should trigger an on-session block. Options are: Confirmed spam, Bulk spam, Virus, High probability virus.

In the SenderID threshold settings for on-session blocking policy, specify the threshold for each classification and the action that should be taken when the SenderID threshold is crossed. Options include:

- None (the message is not blocked)

- Tempfail

- Permfail
