Mail2Web is a gateway between email and Web service for places where no direct Internet connection is available, but email can be used. This script can be installed in the .forward file of an email-enabled Unix account and will then translate simple email commands into Web page fetches. Authorized users are identified by their "from" address and a password in the subject line.

ZEG, which stands for "Zero Effort Groupware", is a virtual appliance of SOGo intended to provide a complete out-of-the-box testing environment. SOGo is a collaboration suite (or groupware) with speed and scalability in mind. It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (CalDAV, CardDAV and GroupDAV, vCard, and vCalendar/iCalendar) and thereby enables the use of many clients and the reuse of any existing infrastructure. The appliance is prepared to be imported in VirtualBox but can also used in VMWare.
Response is a set of tools to handle automatic email responses, also called "Out of Office", "Vacation", or "Autoreply" messages. Response tries hard to do that the correct way, i.e. not responding to messages that should not be responded to. All of the validation code can be easily modified to suite your needs, but the project tries hard to ship sane defaults. It is designed for many virtual users and multiple mail servers, but works just fine for small deployments. Configuration and response state is stored in an RDBMS.
foldroid is a mail folder selection tool. For people who use mutt or a similar text mode mail reader, foldroid is a convenient tool to navigate through your mail folders. It shows how many messages are in each folder and how many of them are new. This, combined with a tool like procmail to sort mail messages of mailing lists into separate folders, makes selecting the right folder to read easy. Foldroid works best when you run it in a screen session, because it then starts every instance of mutt in its own screen.
Kwaga BirdsEye is a desktop widget that recognizes email messages that matter and alerts the email recipient when the recipient receives an email that asks for something or requests a meeting, or when the recipient receives an email with a reply to an important email. The desktop application works whether or not the user has connected to email Inboxes. It supports Gmail and Google Apps, free.fr, and Yahoo mail accounts. Up to five accounts may be used. Kwaga BirdsEye automatically detects and prioritizes the people the recipient has already communicated with in the past (a.k.a. "trusted sources").
