NeoMail is a web-based e-mail client that can be installed on any UNIX mail server that is also running a web server.    Sending/receiving messages with multiple attachments. Inline image attachment display. Friendly, attractive, icon-based user interface -- If you don't agree, you can create your own using the built-in interface template support! Multiple language support, including English, Spanish, German, French, Hungarian, Italian, Dutch, Polish, Portuguese, Norwegian, Romanian, Russian, Slovak, and more can be added easily. Multiple folders, default ones like SENT and TRASH, and support for user-created ones as well. Configurable limits on outgoing attachment size, folder disk usage, addressbook size... User preferences, including number of messages displayed on a page, language, signature, and style (color scheme of interface). Each user has their own address book, which can be popped up during message composition in a separate window, without disrupting your e-mail in progress. Users can even import their address book from Outlook Express or Netscape Mail in CSV format. Many more little niceties you might not expect to get in a webmail client.
