I have an email account that gets nothing but 30-40 spam emails from around 5 spam campaigns every single day. I got fed up to the point of not using it for anything anymore. How can I configure postfix to be as annoying for the sender as possible? Like tarpitting, that is slowing down connections to tie up connections on the sending server or greylisting to make it try again. Can I request or send stuff that will consume memory or cycles on the sending server? Other evil tricks? Connect to their unsubscribe link a bunch of times with random query strings?
I'm quite sure the emails come from automatically spun up cloud instances from domains like .xyz and .icu, with a new domain every day. The domain of the sender matches the sending server and it seems their DKIM is configured correctly
