Show HN: Outis – Fight AI spam by sending fake "user unknown" bounce emails

Outis fights spam generating and sending a fake "user unknown" bounce for an email you received, so the sender believes your address does not exist. Of course this isn't a novel idea, I created a similar program back in 1998–1999 (actually, with a slightly different purpose), but I decided to revive it because it should work quite well with the recent trend of automated emails generated by AI, where the sender might expect a reply; it helps remove your email address from their list. I don't have strong evidence about its effectiveness, but I'm testing it for few weeks and the spam noise seems to be reduced; I don't receive similar or followup emails any more. Any idea on how to improve it? :) Comments URL: https://news.ycombinator.com/item?id=49934692 Points: 2 # Comments: 0
