Today I was a little annoyed by spam that keeps plaguing my email servers, and I decided to make it a little more maintainable.
I remembered another HN thread where somebody uploaded a gist of spam domains [1] and decided to do something similar to avoid spam from large-scale spam providers like salesforce, AWS or digitalocean.
Currently, there's no WHOIS integration yet, but I'm probably gonna work on this when I receive more spam.
Maybe someone here has a nice hosts block list and wants to contribute?
