I have some problems with the validation of a Email.

In my Model:

 [Required(ErrorMessage = "Field can't be empty")]
        [DataType(DataType.EmailAddress, ErrorMessage = "E-mail is not valid")]
        public string ReceiverMail { get; set; }

In my view:

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

 @Html.TextBoxFor(m => m.ReceiverMail, new { @placeholder="E-mail"}) <br />
            @Html.ValidationMessageFor(m => m.ReceiverMail)

Now it is correctly showing me "Field can't be empty" when you leave the field empty. But when you fill in an invalid email address like: "fwenrjfw" then the form does not say "E-mail is not valid".

How can I get the form to validate the input as an email address? I am looking for some help with this.

You need to use RegularExpression Attribute, something like this:

[RegularExpression("^[a-zA-Z0-9_\\.-]+@([a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$", ErrorMessage = "E-mail is not valid")]

And don't delete [Required] because [RegularExpression] doesn't affect empty fields.
