Hi,

We are using Google Auth2 for sending email and getting below error.

Error: The server has responded with negative reply. The server responded: 555 5.5.2 Syntax error

sample code for c# as below

Smtp mailer = new Smtp();
               mailer.SmtpServers.Add("smtp.gmail.com", null, xoauthKey, AuthenticationMethods.SaslOAuth2);

               // Logging is not necessary but useful for debugging.
               mailer.Log.Enabled = true;
               mailer.Log.Filename = @"C:\Temp\log.txt";
               mailer.Log.HidePasswords = false;
               mailer.Log.Clear();

               Console.WriteLine(mailer.IsSslConnection);
               mailer.From.Email = userEmail + " <" + userEmail + ">"; // + " <" + userEmail + ">"; //+ "<" + model.FromEmail + ">"
               mailer.From.DisplayName = "Dinesh Bhai";
               mailer.To.Add("swapnalchonkar@gmail.com");
               mailer.Subject = "empty email to myself";
               mailer.BodyHtmlText = "Hello World !!!";

               // For async/await version, see GoogleOAuthWinForms sample.
               mailer.Send();

Looks like xoauthKey isn't valid, but it's not clear from your code how you're obtaining one. Can you post the relevant code?
