Hello,
account1 is a paid business email for which I have configured a google cloud service account so I can automate.
When I smtp from account1 everything is logged as being sent from account 1 but in the inbox I receive the email as being sent but account2 (which is a free personal account I also own).
If I "View Original" into google it shows everything as being sent from account2 (free) with a single hint that this was actually sent by account1
X-Google-Original-From: account1
Which means google silently changed my From from the original business account1 to the free account2.
Why is this happening?
I want to mention that I have given the correct "Domain Wide" permissions to the service account which is automating this.
Thank you,
