Email verification with simple verification is not the same client as serveride

Question

I use FluentValidation to test my models on both the client and server side. I am in the latest version:

FluentValidation.MVC5

at the time of writing which

5.5.0.0

I have the following validator simplified:

public class MyViewModelValidator : AbstractValidator<MyViewModel>
    {
        public MyViewModelValidator()
        {
                RuleFor(x => x.Email)
                    .EmailAddress().WithLocalizedMessage(() => MyResources.Validation_Email_NotValidAddress)
                    .NotEmpty()
                    .WithLocalizedMessage(() => MyResources.Validation_Email);
        }
    }

The client side seems to perform some basic verification, for example, that it will not accept anything without text on both sides of the "@" character, however it will accept something like test@test.

The problem occurs when I send this data, I have the following in the controller:

    if (!ModelState.IsValid)
        throw new Exception("Model validation error");

This means that the model is invalid due to the email address test@testand throws an error. Therefore, it seems that my front-side validation is weaker than my server-side validation.
