I’ve been trying to fix this for days and I still don’t find a solution. I have set Mailgun, modified app.yml, the settings on Discourse and so on, every little advice on this forum and beyond.
I can receive the emails of my install on any domain email except gmail.
Also, when I change the values on app.yml they don’t appear as change on
/admin/email I don’t know if that’s right.
Could anyone help me out with this somehow?
