That has happened to me… twice. Once they sent spam to abuse@<domain> and once to postmaster@<domain>. Both of those are “well-known” addresses that received one spam mail each.
Having your own domain with a catch-all address is rare enough that spammers don’t seem to try to target it.
Meanwhile I set up straight-to-spam rules for a handful of companies that leaked my email address. Very useful.














An LLM trained on the PoE ingame chat would try to solve all my problems by asking to buy my Kaom’s Sign Coral Ring for 1ex.
