I´m trying to send an email through gmail using this code:

MailMessage msg = new MailMessage();
            msg.From = new MailAddress("admin@XXXXXX.com");
            msg.To.Add(destinos);
            msg.Subject = "XXXX";
            msg.Body = "XXXX"
            //msg.Attachments.Add(new Attachment(archivo + ".pdf"));
            //msg.Attachments.Add(new Attachment(archivo + ".xml"));
            SmtpClient client = new SmtpClient("smtp.google.com", 587);//587 465 
            client.EnableSsl = true;
            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            client.Credentials = new System.Net.NetworkCredential("admin@XXXX.com", pass);

                client.Send(msg);

However it fails, giving this exception:

16/07/2012 03:45 p.m. ERROR: Error al enviar correo. Data: System.Collections.ListDictionaryInternal System.Net.WebException: No se puede resolver el nombre remoto: 'smtp.google.com'
   en System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout)
   en System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback)

   en System.Net.Mail.SmtpClient.GetConnection()
   en System.Net.Mail.SmtpClient.Send(MailMessage message) Exception actual: Void Send(System.Net.Mail.MailMessage)

The exception is in spanish, I don’t really like that either but it says something like:

There was an error when sending the mail, Couldn't resolve host smtp.google.com

I have checked the current google parameters and they look good for this code.
