In short: are email end-to-end tests a thing?
As part of my CI I would like to run email integration/end-to-end tests: the app would send it to some SMTP server and then hits maybe an endpoint where it would check if SMTP server got the email. I have hard time finding anything similar on the net though... Did you hear about something like that, or maybe it just doesn't make any sense to test something like that? Emails notifications are crucial in our app, maybe there are some other ways to make sure that they work (we do have unit tests)?
The SMTP server is Postfix, the app is built with Python/Pyramid.
