Change the email settings

Continuing the discussion from Goodbye Sparkpost; how can I change the email settings from admin panel?

Is there a way? :thinking:

I checked:


SMTP settings are set on the app.yml file.

Yes, so for edit that file… there is not admin panel option available, is it?

No, that is set on the yml file and not on the site settings.


Hey @Falco, thanks for the responses here. After changing the app.yml file what should I do to ensure those changes are valid and integrated into my forum?


Hello Luca, go to:
And check the settings.

After that, go to, and new register form, put an email (new one, use your friend’s mail, or something else), and check if the email arrives fine.
