email doesnt send in mvc but works in asp.net webform

I have switched to ASP.NET MVC recently. I want to send email confirmation when people sign up to my website.

So I uncomment the code that ASP.NET MVC has by default for this and add configuration in web.config but that doesn't work and I kept having this error:

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

I created an asp.net webforms and tried to send email from that project and that worked. So I copied the code that I had in my page load for sending email in webforms and put it in register action in account controller but I had that error again.

I really can't understand why I get this error in ASP.NET MVC, but the exact same code works fine in webforms.

This is the code in ASP.NET MVC register action:

public async Task<ActionResult> Register(RegisterViewModel model)
{
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser { UserName = model.Email, Email = model.Email, BirthDate=model.BirthDate };

            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);

                // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                // Send an email with this link
                //string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                //var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                //await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

                //create the mail message 
                MailMessage mail = new MailMessage();

                //set the addresses 
                mail.From = new MailAddress("[email protected]"); //IMPORTANT: This must be same as your smtp authentication address.
                mail.To.Add(user.Id);

                //set the content 
                mail.Subject = "This is an email";
                mail.Body = "This is from system.net.mail using C sharp with smtp authentication.";
                //send the message 
                SmtpClient smtp = new SmtpClient("mail.wwwebco.com");

                //IMPORANT:  Your smtp login email MUST be same as your FROM address. 
                NetworkCredential Credentials = new NetworkCredential("[email protected]", "MyPassWord");
                smtp.Credentials = Credentials;
                await smtp.SendMailAsync(mail);

                return RedirectToAction("Index", "Home");
            }
            AddErrors(result);
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

and the code that I had in the asp.net webforms app and works fine is:

protected void Page_Load(object sender, EventArgs e)
{
    //create the mail message 
    MailMessage mail = new MailMessage();

    //set the addresses 
    mail.From = new MailAddress("[email protected]"); //IMPORTANT: This must be same as your smtp authentication address.
    mail.To.Add("[email protected]");

    //set the content 
    mail.Subject = "This is an email";
    mail.Body = "This is from system.net.mail using C sharp with smtp authentication.";
    //send the message 
    SmtpClient smtp = new SmtpClient("mail.wwwebco.com");

    //IMPORANT:  Your smtp login email MUST be same as your FROM address. 
    NetworkCredential Credentials = new NetworkCredential("[email protected]", "MyPassWord");
    smtp.Credentials = Credentials;
    smtp.Send(mail); 

}

I am really stuck with this problem. Please help!

Thank you.

UPDATE:

Why are you using user.Id and not model.Email?

If you have any blank or missing details, this can cause an error?

Original:

You should change the mail.From to be mail.Sender.

Are you loading the ASP.NET Web Forms and the MVC to the same host environment? Could one be blocking port 25, or requiring SMTP to be sent over HTTPS?

For HTTPS you would need to change your port number, usually port 465, but might be different, depending on your mail sender.

If your SMTP server has restrictions, try using SendGrid, which has a free account.
