Dear Mr. Tuomi
Google is responding to me as Unauthorized.
So I need to send my credentials such as access token in the request
parameter for authentication in google?s Get User API request.
But I don?t know how to configure dovecot to achieve that.
Could you please help me with this?
Best regards,
