SquirrelMail is a light-weight, proven, and reliable web mail client. It provides you with personal
address books, LDAP address look-ups, plenty of customizable options, themes, and more. SquirrelMail
should provide you with a fast interface, especially if you have a lot of e-mail. No frills, just
proven reliability for almost a decade. You may want to use this client if you have a slower computer,
slower internet connection, or need to load a larger e-mail box.
RoundCube is a newer web mail client that utilizes many new types of technology. It hasn't been
proven as reliable as SquirrelMail, but offers a much nicer interface with more features like
drag-and-drop interfacing, as well as hot-keys to interface with your e-mail easier. This client
feels more like a desktop e-mail client and less like a traditional web mail client. It also supports
personal address books, customizable options, LDAP address look-ups and spell-checking.
