Maybe not -- I'm not a programmer / not great at command line stuff, so find procmail pretty intimidating. I'm getting LOTS of spam on a topic (bitcoin) recently -- enough that it would save me a lot of time and trouble to just block any email with the chain "bitcoin" (case insensitive). I can't do it in the client (I'm using the Mail extension in the Vivaldi browser).
Is Procmail the only real way to deal with creating mail rules, or are there other, less intimidating ways to approach this at the server level?
