Yale WebMail beta

From Chuck: "IMPv4 is based on the PHP scripting language, which historically has been perceived as providing scant support for unicode implementations. PHP is getting better about this though, and the minimum version required for use with IMPv4 is PHP 4.3.0. The latter is probably what Yale is depending on using now, but there is a later release of PHP, 5.0, which could also be used with IMPv4 and would (I think) offer better unicode support. In any case, all the horde products are completely open source, so there's nothing stopping us (except putting in the dev time) to customize it."
