If you are running Microsoft Exchange and need a quick way to determine what mailboxes are forwarding email, then this Powershell script is for you. In order for this script to run, you will need at least the Exchange Management tools installed on the computer from which the script will be run.
Note: this script can be easily extended to email the results using my previous article on how to Send Email With Powershell.
