テストこのコード：

 MailMessage mail = new MailMessage(); 
     SmtpClient SmtpServer = new SmtpClient("smtp.live.com"); 

     mail.From = new MailAddress("mawlud.f.m@hotmail.com"); 
     mail.To.Add("mawlud.f.m@gmail.com"); 

     mail.Subject = "Mail Subject"; 
     mail.Body = "Mail Body"; 

     SmtpServer.Port = 587; 
     SmtpServer.Credentials = new System.Net.NetworkCredential("mawlud.f.m@hotmail.com", "Write Your Password"); 

     SmtpServer.EnableSsl = true; 
     SmtpServer.Send(mail);
