Put this into our whole domain blocklist, but can confirm only about a 20% reduction. In the end, it's playing whack-a-mole.

I've played with the idea of building a managed incoming email gateway SaaS (Codename Project S.H.I.E.L.D) where you can just exclude whole cohorts of unwanted inbounds (recruiting, offshoring, monetization, linkbuilding) powered by Machine Learning, but I'm too busy to build it any time soon.

If someone's in and wants plans from my drawer, I'll be a paying first customer ;-)

I built something like this for my personal use that filters based on domain/sender and provides per use addresses. There is no machine learning, but it has a sender learning period per address and can reject all new senders.
