AUTORESP is a server for XFBB. It simply sends a predefined message back to any user that sends a message to it.
This can be used to inform users that the server they were trying to use is either not available on your FBB system or that it is currently disabled.

Note: All my XFBB programs are provided as-is, I have not used them for over 10 years and have no way to test them, I am able to provide very limited support in trying to use them.
