[otrs] Adding a new postmaster module

I've created a new postmaster module. After reading through the documentation I'm not clear what else I need to do in order to add it into OTRS and make it active. I put the .pm file in the /opt/otrs/Kernel/System/PostMaster/Filter/ directory. Is there additional information needed within OTRS to get it working? Such as changing a config file or updating a source file to tell it to load when OTRS is executing?
