I think you mean collecting all email addresses and connecting them (manually) to the correct mailbox in the config of Postfix (or equiv, I have no idea what is used at my hosting provider)? That sounds like a doable one-time action if all new addresses use proper sub-addressing.

I do know that sub-addressing with a special character is nowadays a normal, better, way to do it. Unfortunately we have used this system for a very long time, starting around 2005... So there are a lot of existing email addresses. Then set them up in virtual (or if not using postfix, whatever equivalent) and stop allowing new ones.
This is FAR simpler and workable than what you are trying to do, and has the added benefit of working very simply and having nearly no impact on your server.
