SPAM BLOCKING by IP address range
In addition to the current spam filtering options, it would be nice to be able to completely BLOCK receiving email from specific IP ranges. (Reject the message at the SMTP level.
I have a list of about 60 /24's that only deliver spam to my inbox. Since many of them are controlled by spammers, they spew garbage with an endlessly rotating series of domains, so blocking by domain name is impossible. also, some of these sources operate out of several countries, so country based blocking would have too much collateral damage. (Also allow import and export of the blackslist vis .csv) My current provider allows blocking with wildcards such as X.Y.Z.% will block the /24: X.Y.Z.* I literally get 30-40 spam message per day from these ranges. With this feature I should be able to migrate to Protonmail completely

It would be even better if you could block by country.
I'm already tired of checking the sender of spam mail and seeing that it only comes from one country...
