I am having a problem using Internet Explorer 8 (IE8) to open mailto links with long messages.
After the user clicks on the link, IE changes to an about:blank page

I never could get the location.href = mailtoHref hack to work. However, I have found that following works.
$('body').append($('');
$('#mailtoHack').remove();
</code></pre>

<p><strong>EDIT</strong></p>

<p>Here is a way to do it without jQuery:</p>

<pre><code>function mailtoHack(href) {
    var iframeHack;
    if (href.indexOf("mailto:") === 0) {
        iframeHack = document.createElement("IFRAME");
        iframeHack.src = href;
        document.body.appendChild(iframeHack);
        document.body.removeChild(iframeHack);
    }
}
</code></pre>

<p>And, for good measure, here is a Knockout custom binding usable as <code>data-bind="mailto: foo"</code>:</p>

<pre><code>ko.bindingHandlers.mailto = {
    init: function (element, valueAccessor) {
        ko.utils.registerEventHandler(element, "click", function (e) {
            var href = ko.unwrap(valueAccessor()), iframeHack;
            if (href.indexOf("mailto:") === 0) {
                iframeHack = document.createElement("IFRAME");
                document.body.appendChild(iframeHack);
                document.body.removeChild(iframeHack);
            } else {
                e.preventDefault();
            }
        });
    }
};
</code></pre>
    </p>
