I have set up a Gmail OAuth App and OAuth Client Ids credentials. This is done under the gmail account owned by someone who we will call [email protected].
When I send an email via that connection to any email (we will say [email protected]), the email goes to [email protected] but an exact copy is sent to [email protected] as if he was BCC's on it. Greg's copy has a send to of [email protected].
I have gone through this process twice trying to see if I messed up in my creation. As I have done a couple of these before, I am confused as to what is going on with this one. Is the problem related to the fact that I created all the Gmail Oauth app and clientId's while logged in as greg instead of myself?
What/where do I look to see why emails being sent via greg's gmail API are apparently being BCC'd to him also? They should only go to the recipient.
I have created a 2nd Gmail Oauth App and Client Id and tested with that. The same problem exists. I was expecting only the recipient to get the email.
One test I run is using a google apps script which contains:
GmailApp.sendEmail(recipient, subject, body);
I then changed from using the Google API to using a an SMTP server (smtp.google.com) with the greg gmail username and an App password. The same results are happening.
