Department email settings (specifically, modifying the "From" email address and name) from version 2 have been moved to another section of the software in version 3.

If you installed a fresh copy of version 3, you'll see a few default notification messages already in the system. You can modify these messages, or add new messages. This is where you can adjust the "From" email address and name.
