phlyMail Lite is a webmail client written in PHP. Through the use of AJAX and modern XHTML it offers a GUI similar to that of desktop email programs. You can store as many email accounts as you like, be it POP3 or IMAP ones. Additionally it features an address book, a calendar and a files manager, where you can upload and organize files of any kind (images, videos, documents). A few additional themes are available, too.
