As far as I can tell Fastmail comes pretty close, I have as many email addresses as I want on multiple domains and a bunch of routing rules for €4/mo.

How do you do that on Fastmail? I only see per email address pricing with each email address cost close to what you pay.

Oh, maybe I didn't mean the same as you. I can create as many email addresses as I want, but they all go to the same inbox. Multiple inboxes would cost more.

In the pricing page it is listed in the "Individual" plan as "+ Extra email addresses for personal and work".

Edit: It is possible to create an extra email address and set it up so that all emails it receives are sent to a different external email address
