MailMessage using.System.Net.Mail not working for me

MailMessage using.System.Net.Mail not working for me

I am new here and new to MVC4. There seem to be little guidance in MVC4 and I am trying to learn it on my own. So far I have created a site that is working well except a few glitches that I would like to get worked out and hopefully learn from this.
SO I created a simple contact form. But it is useless. I need it to send the information in the form to my email. Very easy process in PHP, and HTML but .NET seems to be very difficult.
Here is what I have in my Controller for the contact page (contact form)
   [HttpPost]
    public ActionResult Contact(ContactsModel model)
    {
        if (ModelState.IsValid)
        {
            InsertContact(model.Name, model.Phone, model.Email, model.Comments);

            MailMessage message = new MailMessage();
            message.From = new MailAddress(sender1@foo.bar.com);
            message.To.Add(new MailAddress(lotusms@outlook.com));
            message.Subject = "This is my subject";
            message.Body = "This is the content";
            SmtpClient client = new SmtpClient();
            client.Send(message);

            TempData["notice"] = "Someone will reply as soon as possible.";
            return RedirectToAction("Index", "Home");
        }

        return View();

    }
And this is my actual form code in my view
@using(Html.BeginForm())
{
@Html.LabelFor(model => model.Name)<br />
@Html.TextBoxFor(model => model.Name)<br />
@Html.ValidationMessageFor(model => model.Name)<br />

@Html.LabelFor(model => model.Phone)<br />
@Html.TextBoxFor(model => model.Phone)<br />   
@Html.ValidationMessageFor(model => model.Phone)<br />

@Html.LabelFor(model => model.Email)<br />
@Html.TextBoxFor(model => model.Email)<br />
@Html.ValidationMessageFor(model => model.Email)<br />

@Html.LabelFor(model => model.Comments)<br />
@Html.TextAreaFor(model => model.Comments)<br />
@Html.ValidationMessageFor(model => model.Comments)<br />

<button type="submit">SEND</button> //onClick="document.getElementById('contacts-form').submit()"
<button type="reset">CLEAR</button> // onClick="document.getElementById('contacts-form').reset()"
}</pre>
I am getting this error when I submit
    The remote name could not be resolved: 'smtpserver1'
