Filtering spam is a long solved problem and completely trivial. I receive no spam on my self hosted email, and I spend no time at all working on that.
My old unused gmail account however… I recently logged in after more than a year. The spam folder had about 40 emails in it, and the inbox had more than 8000, all of which were spam. Google over self hosting is not a solution to spam.
The other half of your time will be spent filtering through spam
