Can I take the equal sign out?

I am trying to create a feedback form for my web page as below: enter image description here

However, if someone clicks on the 'submit' button, the email the page composes will contain the equal sign like this:

Your name:=abc Your feedback:=efg

Here is my code:

 <form action=mailto:mail@domain.com method="post" enctype="text/plain" name="FeedbackForm">
                Your name: <br>
                <input type="text" size="24" name="Your name:"> <br>
                Feedback: <br>
                <textarea name="Your feedback:" rows="6" cols="50"> </textarea> <br>
                <input type="submit" value="Submit">
 </form>

Is there any way to strip out the equal sign?
