I had the same problem for an application deployed to Microsoft Azure. SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. First I approved all unknown devices (some ip-addresses originating from Ireland) on the following page (signed in as the gmail user): I used the following settings for the client: var client = new SmtpClient('smtp.gmail.com'); client.Port = 587; client.EnableSsl = true; client.UseDefaultCredentials = false; client.Credentials = new NetworkCredential('my_user_name@gmail.com', 'my_password'); It started working only after I set the following property on the smtp-client: client.TargetName = 'STARTTLS/smtp.gmail.com'.
