title: Effective maximum mailto: body lengths
body: <p>There is a maximum length for the text in the &amp;body section of a mailto: link.  According to one of my co-workers, the W3C publish the limit as 256 (I don't have a link to back this up, though).</p>
  
  <p>We're embedding mailto: links in both an e-mail and a webpage and have successfully used more than 256 characters.  After a certain point, though, e-mail clients and browsers start flaking out and refusing to open the link.</p>
  
  <p>I would like to know the actual maximum lengths allowed for the following:</p>
  
  <p>Mail clients:</p>
  
  <ul>
  <li>Outlook (2003, 2007, 2010)</li>
  <li>Eudora (7.1, and/or whatever the latest version is)</li>
  <li>Thunderbird (latest version)</li>
  </ul>
  
  <p>Browsers:</p>
  
  <ul>
  <li>Firefox (3+)</li>
  <li>IE (6, 7, 8)</li>
  <li>iPhone browser</li>
  </ul>
  
  <p>Any and all numbers you can provide will be gratefully received.</p>
