This tool generates email addresses for specific services with your domain name. It is especially useful if you want one email address per service which cannot be guessed and can be recreated easily, if necessary.
This service is available as a Docker image, so you can get up and running in just a minute. The image is available
at ghcr.io/tinyoverflow/catchall-address-generator:latest. All tags can be found at
the GitHub container registry
