I have this script and it's working pretty well. Except now I need it to not give the message on one single external link.

Code JavaScript:
$(document).ready(function() {
 
  // Creating custom :external selector
  $.expr[':'].external = function(obj){
      return !obj.href.match(/^mailto\:/)
              && (obj.hostname != location.hostname);
  };
 
  // Add 'external' CSS class to all external links
  $('a:external').addClass('external');
 
  $('.external').click(function() {
    var link = $(this).attr('href');
 
    $('<div>By clicking \'Okay\' you will be transferred to a web site not controlled by xxxxxxxxxx. xxxxxxxxxxx is not responsible for any of the info or services provided by this web site. The web site you are about to access is not covered by xxxxxxxxxxxxx privacy policy or security statement. <br /> <strong>Are you sure you want to proceed?</strong></div>').dialog({
      title: "External Link",
      modal : true,
      overlay: {
        backgroundColor: '#000',
        opacity: 0.5
      },
      buttons: {
        'Okay': function() {
          $(this).dialog('close').remove();
          window.open(link);
        },
        'Cancel': function() {
          $(this).dialog('close').remove();
          return false;
        }
      }
    });
 
    return false;
  });
});

This works on any "href" external link or link with class of "external". I have one link that needs to be added that is external but needs to appear to not be and not give the warning message.

Can you help me with an exception to this script? Thanks!
