title: Email address in a textbox causes PageRequestManagerServerErrorException
body: <p>I have a <strong>multiline textbox</strong> within an updatePanel. where a user can enter any notes he requires. If he <em>enters</em> an <strong>email address inside angular brackets</strong> then when submitting or cancelling I get a <strong>PageRequestManagerServerErrorException of 500</strong>.  </p>
  
  <p>If he enters an email address in these notes as <code>myaddress.xxx.ca</code> <em>without the brackets</em>, then there is <em>no error</em>.  </p>
  
  <p>The textbox should allow him to enter anything he wants too, it is really just for his notes.</p>
  
  <p>I  have <strong>tried</strong> to the <code>RequestValidation = "false"</code> in the page directive but this <em>does not work</em>.</p>
  
  <p>Any suggestions would be appreciated.</p>
  
  <p>Bryan</p>
