Adds an iFrame to your blog footer to automatically activate any posts written by email.
The iframe used to call the wp-mail.php file is hidden. Its width and height have been set to 0. If you want to check that the plugin has loaded correctly:
<iframe src="http://www.myblog.com/myblog/wp-mail.php" name="mailiframe" width="0" height="0" frameborder="0" scrolling="no" title="">
Yes, I'm sure it works :)
If you're using caching on your site, such as WP Super Cache, then you may have to clear the cache before you can see the code.
