Simply dispose the MailMessage and SmtpClient objects after the .Send() function.

SmtpClient smtpClient = new SmtpClient("server", 25);
smtpClient.UseDefaultCredentials = true;

MailMessage message = new MailMessage("ToAddress","FromAddress");
message.Subject = "Test email";
message.Body = "Test email";

smtpClient.Send(message);

message.Dispose();
smtpClient.Dispose();
