Send async e-mails

Question

I am using ASP.NET MVC 3 with MVCMailer, I tried to send e-mails using SendAsync, but actually it still take longer.

So I am trying to use Task.Factory like the code

You dont need tasks. SendAsync is asynchronous and use another thread self. Tasks dont accelerate you mailing.

UPDATE: When i resolve same problem i use task and synchronous send. It seems that SendAsync was not so asynchrous. It is sample of my code (it is not want HttpContext):

public void SendMailCollection(IEnumerable> mailParams)
    {
        var smtpClient = new SmtpClient
        {
            Credentials = new NetworkCredential(_configurationService.SmtpUser, _configurationService.SmtpPassword),
            Host = _configurationService.SmtpHost,
            Port = _configurationService.SmtpPort.Value
        };

        var task = new Task(() =>
                                {
                                    foreach (MailMessage message in mailParams.Select(FormMessage))
                                    {
                                        smtpClient.Send(message);
                                    }

                                });
        task.Start();
    }

    private MailMessage FormMessage(Tuple firstMail)
    {
        var message = new MailMessage
            {
                From = new MailAddress(_configurationService.SmtpSenderEmail, _configurationService.SmtpSenderName),
                Subject = firstMail.Item1,
                Body = firstMail.Item2
            };
        message.To.Add(firstMail.Item3);
        return message;
    }
