Sending mail with Postal library in MVC 5 - asp.net-mvc-5

Question

I'm using the Postal library to send emails from the contact page. I have the following code:
ContactEmail
using AccessorizeForLess.ViewModels;
using Postal;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace AccessorizeForLess.Models
{
public class ContactEmail : Email
{
public string To { get; set; }
[DataType(DataType.EmailAddress)]
[DisplayName("Email Address")]
[RegularExpression(#"^([\w\.\-]+)#([\w\-]+)((\.(\w){2,3})+)$", ErrorMessage = "The Email field is not valid, Please enter a valid email address!")]
[Required(ErrorMessage="Email address is required.")]
public string From { get; set; }
[DisplayName("First Name")]
[Required(ErrorMessage="Please provide your first name")]
public string FirstName { get; set; }
[DisplayName("Last Name")]
[Required(ErrorMessage="Please provide your last name")]
public string LastName { get; set; }
[DisplayName("Subject")]
[Required(ErrorMessage="Please select a topic")]
public SelectList Subject { get; set; }
public string SelectedSubject { get; set; }
[DisplayName("Message")]
[DataType(DataType.MultilineText)]
[Required(ErrorMessage="PLease provide a message for the email")]
public string Message { get; set; }
public List<EmailSubjectViewModel> Subjects { get; set; }
}
}
EmailSubjectViewModel
namespace AccessorizeForLess.ViewModels
{
public class EmailSubjectViewModel
{
public int Id { get; set; }
public string Subject { get; set; }
}
}
ContactController
public ActionResult Index()
{
List<EmailSubjectViewModel> Subjects = new List<EmailSubjectViewModel>()
{
new EmailSubjectViewModel(){Id=1, Subject="Website Issues"},
new EmailSubjectViewModel(){Id=2, Subject="Order Issue"},
new EmailSubjectViewModel(){Id=3, Subject="Product Question"},
new EmailSubjectViewModel(){Id=4, Subject="Returns Questions"},
new EmailSubjectViewModel(){Id=5, Subject="Other"}
};
ContactEmail email = new ContactEmail()
{
Subjects = Subjects
};
return View(email);
}
public ActionResult Send(ContactEmail email)
{
ContactEmail e = new ContactEmail();
e.From = email.From;
e.FirstName = email.FirstName;
e.LastName = email.LastName;
e.SelectedSubject = email.SelectedSubject;
e.Message = email.Message;
e.Send();
return View();
}
And last but not least my view:
#model AccessorizeForLess.Models.ContactEmail
#{
ViewBag.Title = "Contact";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Contact</h2>
#using (Html.BeginForm("Send", "Contact", FormMethod.Post))
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>AccessorizeForLess.net
<img src="~/Content/icon-facebook.png" /></h4>
<div style="color:red;font-weight:bold;">#ViewBag.Message</div>
<hr />
#Html.ValidationSummary(true)
<div class="form-group">
#Html.LabelFor(model => model.FirstName, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.FirstName)
#Html.ValidationMessageFor(model => model.FirstName)
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.LastName, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.LastName)
#Html.ValidationMessageFor(model => model.LastName)
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.From, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.From)
#Html.ValidationMessageFor(model => model.From)
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.SelectedSubject, "Category", new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownListFor(model => model.SelectedSubject, new SelectList(Model.Subjects, "Id", "Subject"), "- Please Select -")
#Html.ValidationMessageFor(model => model.SelectedSubject)
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Message, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Message, new { #cols = "25", #rows = "55" })
#Html.ValidationMessageFor(model => model.Message)
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Send" class="btn btn-default" />
</div>
</div>
</div>
}
Oops almost forgot the section in my web.config
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="admin#accessorizeforless.net">
<network host="smtp.gmail.com" port="587" enableSsl="true" defaultCredentials="true" userName="***********#gmail.com" password="**********" />
</smtp>
</mailSettings>
</system.net>
Now when I fill out the form and click send I get the following error:
System.Net.Mail.SmtpException: The SMTP server requires a secure
connection or the client was not authenticated. The server response
was: 5.5.1 Authentication Required.
I thought I was setting the authenticatioon credentials in the web.config?

Answer 1

I had to change defaultCredentials to false in the web.config and all seems to be working right now.
