Sorry to read that you’re dealing with this. My primary email is apart of some vast international spam program where the mail servers responsible for sending me spam forge headers, falsify source record information, lie about which downstream service provider is hosting them, etc. It’s really quite interesting, but more so than that, it’s annoying.

I pondered my problem for a few days, thinking about what sort of external service I could use to surgically remove these numerous, daily, very specifically identifiable spam emails before I stumbled on a thread on StackOverflow where some people discussed using Google App Scripts to do this very thing.

I’d recommend searching the web for that sort of topic. You’ll find that there’s a way to set up an hourly script job that will wipe this spam completely off your mailbox and find some peace.

Hope this points you in the right direction. The idea of having to use yet another Google service to fix an existing separate one is such a stupid labyrinthine experience, but at least it beats having to set up a job on a VPS for this.

If you had this issue with another mailbox service provider, a VPS approach would probably be necessary, though.
