Must the “notification email” domain match the SMTP server setting in app.yml?
Going to: Rasando I get:
[Sender] 550-Sorry 18.104.22.168. The "MAIL FROM" email address email@example.com /
What I would like to do is setting the notification email on @gmail.com and use my domain Smtp settings. Do I have to change something in the DNS (SPF, DKIM) on my domain?
