If you're here because you got some spam that looks like it came from warmenhoven.org, it didn't. Spammers are using fake warmenhoven.org addresses to send their spam. They're not using my servers, so there's no way I can stop it.
I turned off the catch-all address on warmenhoven.org and now I no longer receive bounces, so to be honest I'm not even sure if the domain is still being abused.
