Hey there, I just switched from vexim to Exim4U on my dedi and took the opportunity to tidy up the markup in the public_html files. So if you are interested in customizing the look of your Exim4U installation you might want to try this github repo: https://github.com/mkay/Exim4UI Styling is kept to a minimum and is done with a stock bootstrap* 2.2.2 .css which can easily be removed/replaced/extended with your own styles. Also included the BS .js for some basic tabbing and a dropdown menu. It should be a good starting point if you want to build a custom Exim4U layout. If you use a stock Exim4U 2.1.1 installation you should be fine just replacing the files in your /exim4u directory. All included PHP code and other exim4u files remain untouched. *http://twitter.github.com/bootstrap/ Mika
