Since version 10.7 of ProVide it is now possible to limit the use of the FTP commands HELP and FEAT for unauthenticated users, this can be done by altering the following values in the Settings.ini configuration file:

[Allow FEAT before authentication]
True
[Allow HELP before authentication]
True

Simply setting these values to False will disable the commands for unauthenticated users.

*Note that changing these values is not recommended because it will cause clients that expect this functionality available to not be able to connect.
