Hm interesting, do you want to tell why this helps out a lot perhaps?
I have a separate email I only use to get government and public services (gas, electricity) stuff and it still receives a few hundreds of spam a week. At this point I kinda feel whitelisting the mail I want to read is the only sane option, so getting hundreds or thousands of spam mail makes little difference, while managing a portofolio of addresses is a chore.
