Can the webplayer send emails?

I've searched my question and found no conclusive answers.

I've implemented a c# script that succesfully sends email from the editor and standalone builds, but it relies on libraries that are not avaliable on the webplayer build (System.Net.Mail?).

My implementation follows:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using System;
 using System.Net;

 #if !UNITY_WEBPLAYER
 using System.Net.Mail;
 using System.Net.Security;
 using System.Security.Cryptography.X509Certificates;
 
 public class MailHelper : MonoBehaviour
 {
     #region SINGLETON
     private static MailHelper _instance;
     public static MailHelper Instance
     {
         get
         {
             if (!_instance)
                 _instance = GameObject.FindObjectOfType(typeof(MailHelper)) as MailHelper;
             return _instance;
         }
     }
     #endregion
 
     public void sendMailTest()
     {
         MailMessage tempMail = new MailMessage();
         SmtpClient _smtp = new SmtpClient("smtp.gmail.com");
 
         tempMail.From = new MailAddress("[SOME EMAIL ADRESS]");
         tempMail.To.Add("[SOME EMAIL ADRESS]");
         tempMail.Subject = "subject";
         tempMail.Body = "text";
 
         _smtp.Port = 587;
         _smtp.Credentials = new System.Net.NetworkCredential("[SOME EMAIL ADRESS]", "[SOME PASSWORD]");
         _smtp.EnableSsl = true;
         ServicePointManager.ServerCertificateValidationCallback = 
             delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
         {
             return true;
         };
         _smtp.Send(tempMail);
         Debug.Log("sent");
 
     }
 }
 #endif

Can someone point the way to a similar code that works both on standalone and webplayer builds?

Thanks in advance.
