Email confirmation in ASP.NET mvc5 without sendgrid

Question

The name pretty much talks about it. Is there a way to add email confirmation to my application without using the send grid? my Azure account will not allow me to use it, says that it is not available in my zone, and I can not find another solution.

Answer 1

I have not used sendgrid on my website for the email confirmation service. I do not see the point on small sites with low traffic.

I use the gmail SMTP service and it works fine:

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Net.Mail;
using System.Web;

namespace MyProject.MyClasses
{
public class GmailEmailService : SmtpClient
{
    // Gmail user-name
    public string UserName { get; set; }

    public GmailEmailService():
        base( ConfigurationManager.AppSettings["GmailHost"], Int32.Parse(ConfigurationManager.AppSettings["GmailPort"]) )
    {
        //Get values from web.config file:
        this.UserName = ConfigurationManager.AppSettings["GmailUserName"];
        this.EnableSsl = Boolean.Parse( ConfigurationManager.AppSettings["GmailSsl"] );
        this.UseDefaultCredentials = false;
        this.Credentials = new System.Net.NetworkCredential(this.UserName, ConfigurationManager.AppSettings["GmailPassword"]);
    }


}

}

in the Web.Config file add the following:

  <configSections>

      <appSettings>

        <!--Smptp Server (confirmations emails)-->
        <add key="GmailUserName" value="[your user name]@gmail.com"/>
        <add key="GmailPassword" value="[your password]"/>
        <add key="GmailHost" value="smtp.gmail.com"/>
        <add key="GmailPort" value="587"/>
        <add key="GmailSsl" value="true"/>

      </appSettings>

  </configSections>

In the App_Start \ IdentityConfig.cs file, change the SendAsync method to this code:

public class EmailService : IIdentityMessageService
{
public async Task SendAsync(IdentityMessage message)
{

        MailMessage email = new MailMessage(new MailAddress("[e-mail]", "(do not reply)"), 
            new MailAddress(message.Destination));

        email.Subject = message.Subject;
        email.Body = message.Body;

        email.IsBodyHtml = true;

    using( var mailClient = new MyProject.MyClasses.GmailEmailService() )
    {
        //In order to use the original from email address, uncomment this line:
        //email.From = new MailAddress(mailClient.UserName, "(do not reply)");

        await mailClient.SendMailAsync(email);
    }

}
}

: IdentityConfig.cs:

using System.Net.Mail;

, AccountController :

//
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser { UserName = model.UserName, Email = model.Email };
        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            //Comment the following line to prevent log in until the user is confirmed:
            //await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);

            string callbackUrl = await SendEmailConfirmationTokenAsync(user.Id, "Account confirmation");

            // Uncomment to debug locally 
            // TempData["ViewBagLink"] = callbackUrl;

            ViewBag.errorMessage = "Please confirm the email was sent to you.";
            return View("ShowMsg");
        }
        AddErrors(result);
    }

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


//
// GET: /Account/ConfirmEmail
[AllowAnonymous]
public async Task<ActionResult> ConfirmEmail(string userId, string code)
{
    if (userId == null || code == null)
    {
        return View("Error");
    }
    var result = await UserManager.ConfirmEmailAsync(userId, code);
    return View(result.Succeeded ? "ConfirmEmail" : "Error");
}


private async Task<string> SendEmailConfirmationTokenAsync(string userID, string subject)
{
    // 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(userID);
    var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = userID, code = code }, protocol: Request.Url.Scheme);
    await UserManager.SendEmailAsync(userID, subject, "Please confirm your account by <a href=\"" + callbackUrl + "\">clicking here</a>");


    return callbackUrl;
}        

ShowMsg.cs :

@{
    ViewBag.Title = "Message";
}

<h1 class="text-danger">@ViewBag.Title</h1>
@{
    if (String.IsNullOrEmpty(ViewBag.errorMessage))
    {
        <h3 class="text-danger">An error occurred while processing your request.</h3>
    }
    else
    {
        <h3 class="text-danger">@ViewBag.errorMessage</h3>
    }
}
