                        compemail=false;
                    }
                }
                else
                {
                    document.getElementById('Phone').focus();
                    compphone=false;
                }
            }
            else
            {
                document.getElementById('subject').focus();
                compsub=false;
            }
        }
        else
        {
            document.getElementById('country').focus();
            compContry=false;
        }
    }
    else
    {
        document.getElementById('username').focus();
        compName=false;
    }

}

You need some kind of server-side scripting to send emails.

After it passes validation you can submit your form like this

document.formname.submit();

in your case, this goes at the end of your function

if (comP... == true) {
   form.submit();
}

you can add return false; after each validation if you are using cutom js for example

var first_name = $("#first_name");
        if(!$.trim(first_name.val()).length) {
            first_name.closest('.form-group').removeClass('has-success').addClass('has-error');
            return false;
        }else{
            first_name.closest('.form-group').removeClass('has-error').addClass('has-success'); 
        }

return false will stop the submit button to proceed until the form is not filled.
