Interesting idea, but honest to god I don't really have that big of a spam problem anymore.

O365 is handling 90% of it on our corporate mail; my personal address (which is far older) is hosted at Fastmail and it traps nearly all the spam there, too.

In 2026, I'm much more annoyed by PHONE spam -- though Apple's "who the hell are you and why should ubermonkey take your call" feature has done wonders. (I assume something similar exists in Android.)
