If you are using pattern "^[a-zA-Z0-9-.]+@[a-zA-Z0-9-.]+$" please

replace your pattern "^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$"

it will work properly. 

@model ForumMVC.Models.Customer

@{
    ViewBag.Title = "CheckRegularExpression";

}

<script src="~/Scripts/jquery-2.1.4.js"></script>

<script src="~/Scripts/jquery.validate.min.js"></script>

<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>

<h2>CheckRegularExpression</h2>

@using (Html.BeginForm())

{   
    @Html.LabelFor(m => m.EmailId) 

    @Html.TextBoxFor(m => m.EmailId)  

    @Html.ValidationMessageFor(m => m.EmailId)    

}


using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace ForumMVC.Models
{
    public class Customer
    {
        [RegularExpression(@"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", 
        ErrorMessage = "Please enter a valid e-mail-2 adress")]
        public string EmailId
        {


            get;


            set;


        }



    }


}
