This is expected because you're actually connecting on port 25.

This fields base configuration is of no use unless you're relaying
the mail through a Microsoft Exchange saver.

You're supposed to do something like that (code borrowed
from Abe Gillespie/Mono list):

         static void SendEmail()
         {
             var sender = "sender at gmail.com";
             var email = "receiver at mail.com";
			
             var from = new MailAddress(sender, "Sender");
             var to = new MailAddress(email);
             var mail = new MailMessage(from, to);

             // Set the content.
             mail.Subject = "Subject";
             mail.Body = "Body";

             // Send the message.
             SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
             smtp.EnableSsl = true;
             smtp.Credentials = new NetworkCredential(sender, "password");
             smtp.Send(mail);
          }


You'll need Mono 2.6.x (or 2.4 + Mono.Security.dll from 2.6,
at you own risk) and don't forget to import the
certs as described here
