I am while using php script found here:

http://css-tricks.com/2866-sending-nice-html-email-with-php/

I have submitted it to my server - also it will not send emails properly!

This is exactly what I receive in Gmail: (shows as raw html)

    <body>
        <img src="http://css-tricks.com/examples/WebsiteChangeRequestForm/images/wcrf-header.png" alt="Website Change Request" />
        <table rules="all" style="border-color: #666;" cellpadding="10">
            <tr style='background: #eee;'>
                <td><strong>Name:</strong> </td>
                <td>sd</td>
            </tr>
            <tr>
                <td><strong>Email:</strong> </td>
                <td>myrealemail@gmail.com.au</td>
            </tr>
            <tr>
                <td><strong>Type of Change:</strong> </td>
                <td>Change to Existing Content</td>
            </tr>
            <tr>
                <td><strong>Urgency:</strong> </td>
                <td>Super Wicked Urgent</td>
            </tr>
            <tr>
                <td><strong>URL To Change (main):</strong> </td>
                <td>http://css-tricks.com/2866-sending-nice-html-email-with-php/</td>
            </tr>
            <tr>
                <td><strong>CURRENT Content:</strong></td>
                <td>fdasgdsfg</td>
            </tr>
            <tr>
                <td><strong>NEW Content:</strong> </td>
                <td>sdfgsdgf</td>
            </tr>
        </table>
    </body>
</html>

Can there be any server configurations which i might have to change???

I have also used some wordpress plug ins about this server that appear to achieve the same problem.

Any ideas could be great.

UPDATE:
