What is the intended or typical use for something like this? Testing other applications that send email comes to mind, or am I missing some other uses?
replies(6):
We list it in our docs under 'other services'[0], where it is called out for local development.
Because it has an API[1] you can use it for integration testing as well.
Because it runs in docker, you can use it with any stack, not just ruby.
I would not run it in a prod setting.
