due to

<link rel="related" href="http://anexusit.com/" title="anexusit.com"/>

that ovverride

<link rel="alternate" href="http://anexusit.com/blog/how-send-html-email-drupalmail-function-drupal-6" type="text/html"/>

in aggregator_element_start

My fix is that:

    case 'LINK':
      if (!empty($attributes['REL']) && $attributes['REL'] == 'alternate') {
        if ($element == 'ITEM') {
          if(!$items[$item]['LINK'])
            $items[$item]['LINK'] = $attributes['HREF'];
        }
        else {
          $channel['LINK'] = $attributes['HREF'];
        }
      }
      break;
