just one more thing posteo was mentioned as an alternative i have a posteo account i will drop in a few months their spam policy is to bounce it back to the sender the account own has no say
i also have a mailfence account i will drop a while back i stopped getting mail from my bank i investigated and found the bank mail was generating a false positive virus i informed mailfence and they agreed it was probably the cause of my trouble but they didn't bother to fix it several months later they started passing mail from my bank some times you have to kiss a lot of frogs
