I'm able to add a "Send mail as" email address via the API. I need to set "Reply from the same address to which the message was sent" so that when mail comes in from that address, mail goes back out with that address as the sender. How can we set this via the API?
Is it possible to set this for all mailboxes within a Google Workspace account? Either would be fine for me, either individual user or at admin level as policy for every user.
