A feature like this is automatically baked in to my Fastmail account. "[e-mail]" can become "[e-mail]", and all that email automatically goes to a folder called "banks". https://www.fastmail.com/help/receive/addressing.html

You can do it with google apps too, but it's a little more difficult. Login into an account and setup an alias.

There is a limit to the number of aliases, but you can just create more accounts with aliases that forward to your email.
