Sending email with Smtp client not working on Android

Hey Guys,

Here's the code that I use to send an email from my game. public void SendMail() { var fromAddress = new MailAddress("test@email.com", "Test"); var toAddress = new MailAddress("test@email.com", "Test");

         const string fromPassword = "thePassword";
         const string subject = "this is the subject";
         const string body = "this is the body of the message";
 
         ServicePointManager.ServerCertificateValidationCallback =
         delegate (object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
         { return true; };
 
         var smtp = new SmtpClient
         {
             Host = "smtp.gmail.com",
             Port = 587,
             EnableSsl = true,
             DeliveryMethod = SmtpDeliveryMethod.Network,
             UseDefaultCredentials = false,
             Credentials = new NetworkCredential(fromAddress.Address, fromPassword) as ICredentialsByHost
         };
         var message = new MailMessage(fromAddress, toAddress)
         {
 
             Subject = subject,
             Body = body
         };
 
         message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess | DeliveryNotificationOptions.OnFailure;
 
         smtp.Send(message);
         Debug.Log("Message sent");
     }

The code works great in the editor but when I try it on my Android device, I get a SocketException: Unknown host. Does anybody has an idea on how to fix it ?

Thanks a lot for your time,

Claude
