As an aside, this is why mailing list signups should always have a confirmation step. I've had the same public email address since 1995. I get a ton of spam in my raw emails. The only approach I've found helpful is to use a white/grey/blacklist system: known good are whitelisted, known bad are blacklisted, and you have to manually review the greylist emails. With the usual "this looks like spam" filter, I found I was missing a lot of real mail in the mountains of junk: the ML/algorithmic spam detection just got overwhelmed by the diversity of what I receive to the point it was much less useful.
