MVC4: url routing with email as parameter

Question

I have this url which works absolutely fine on my VS web server

http://localhost:4454/cms/account/edituser/[email protected] (works)

but when I publish this site to IIS7.5 , it simply throws 404.

http://dev.test.com/cms/account/edituser/[email protected]  (does not work)

but the strange things happens if I remove email address

http://dev.test.com/cms/account/edituser/email (works , no 404)

but if I change my url with query string it works fine

http://dev.test.com/cms/account/[email protected] (works)

here is my route entry

routes.MapRoute(
             "Default", // Route name
             "{controller}/{action}/{id}", // URL with parameters
             new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
             new[] { "App.NameSpace.Web.Controllers" }
         );

weird thing I have noticed is that when server throws 404 error page , it is a standards iis 404 page not the one custom one I have.
so I was wondering is there any issue with my route mapping or IIS does not like the url which has email as parameter. but everything works fine with my local dev.
Thanks

Try url encoding the email address in the URL.

EDIT

UrlEncode + Base64?

    public static string ToBase64(this string value)
    {
        byte[] bytes = Encoding.UTF8.GetBytes(value);
        return Convert.ToBase64String(bytes);
    }

    public static string FromBase64(this string value)
    {
        byte[] bytes = Convert.FromBase64String(value);
        return Encoding.UTF8.GetString(bytes);
    }

In your view:

<a href="@Url.Action("MyAction", new { Id = email.ToBase64() })">Link</a>

In your controller

function ActionResult MyAction(string id){
   id = id.FromBase64();
   //rest of your logic here
}
