This panel allows you to specify various security options. The Noretrieves window allows certain files or directories to be blocked from downloading. Hit the Add button and select the file to be blocked. Select an entry and hit Remove to take the file off the list.
Number of allowed failed logins causes connections to be closed after the specified number of login failures.

There is no checking of the given password.
The password must contain an @ character.
The password must be in the form of a valid address.
If the Enforce box is checked, logins failing the test will be denied; otherwise a warning will be issued.
