I was looking on the internet for a IDN-Compatible Trash-Mailer, result: none found.

So I just fired up my own…

In case you are also looking for one, you’ll find it on: displays all messages that arrive on


It’s really simple, I just needed it to do the job, once. If it ends up being used heavily, I might invest some energy to make it more beautiful.

Build your own

Also, if you don’t want to use mine, feel free to get inspired howto build your own trash-mailserver, here’s what I did:

  • Using docker image hmlio/spamsink as a really simple Mail-Server that stores every mail it receives into a folder
  • Using docker image halverneus/static-file-server to serve the received mail files back to any browser
  • Adding a index.html so people would now where they end up and what this is about
  • Bundling it all together into a docker-compose.yml file

All this can be found on github:

Have fun with it!
