Free email client software for linux

Ragnarok Online Client project is a client to the Ragnarok online network.
Ragnarok Online Client is a client to the Ragnarok online network, an MMORPG.
This project only provides an API to be able to program a client without having to understand the protocol itself, and to keep up-to-date just by the library.
Enhancements:
- Made it work with current iRO and improved it to be able to stay online until one kills it ... though no user interaction is implemented yet

The Email Server is designed to provide services offered by its commercial email products, such as IMAP/POP services, Web-Based Email Interface and Administration, Mail Filtering, Spam Blocking and Directory-Based Authentication and Addressbooks.
RH Email Server is fine for businesses and organizations of all sizes. Multiple commercial and educational installations are already using this project. The largest current user load that has been reported is 7,000 + users.

SimpleMail is the easiest e-mail client there is! SimpleMail uses UAP (Unwanted Access Protection) exclusively to SimpleMail that automatically protects you from viruses in e-mails, malicious code in e-mails, and even pictures in spam that my be offensive in content. SimpleMail is compatible with many anti-virus programs, including:

Norton AntiVirus
McAfee VirusScan
Panda Tituanium AntiVirus
AVG AntiVirus (free and professional)
avast! AntiVirus (free and professional)

Normally, you can disable your e-mail protection in your anti-virus, because the UAP technology built in eliminates the need to keep the e-mail protection on.

MailStore is a tool that is built in python and provides a mail proxy for POP3,IMAP4 and SMTP protocols. However, beyond usual proxies, it makes a backup of all incoming and outgoing email and stores them in a Maildir format.

Emails then can be accessed through an IMAP server run on the same machine using the backup Maildirs as mailboxes.

The idea is to provide a realtime , centralized backup of all incoming and outgoing of an organization without the need of user intervention, especially for organizations that use shared email hosting. Many of this hosting providers allow for only POP3 based access of the email.

Secondly, due to its shared hosting environment , there is limited space hence all email ends up being downloaded directly to the client. Any backup effort has to be taken up by the user on a periodical basis. This is prone to problems due to the fact that users might either forget or a data disaster might happen in between a backup cycle.

With a backup proxy like this all email is always available at the backup proxy. Any backup need be done by the administrator only at the proxy server itself. This we believe to be a much more convenient task then backing up user systems individually.

Secondly the MailStore server will always have all the emails the user has sent or received at any point ,hence the backup will always be current. To access the email, a local IMAP server can be run that will provide the user with access to the email that has been backed up. The user may then add this account to their email client and backup all the email out of it locally. (E.g. In Outlook you would probably export all the email in the account). Following that the user will import back the mail back into its original account.

Thirdly , the system requires minimal administrator involvement. It handles the creation of new maildirs for new domain/user combinations. Hence administrators dont have extra config files to play with whenevr new users are added to the system. Whether a user exists or not is left up to the mailserver that mailStore is proxying.

The mailStore system is built in Python. It has been tested with Python 2.3 and 2.4. Any system which support Python 2.3/ Python 2.4 should be able to run it.

Ciphire Mail is an email encryption tool. It works in conjunction with your existing email client. It operates seamlessly in the background and does not interfere with normal email routines.
Ciphire Mail program encrypts and decrypts email messages, and can digitally sign each message to provide authentication and guard against identity theft.
It resides on your computer, between your email client and your email server, transparently encrypting/decrypting and digitally signing your email communication. It runs on Windows 2000/XP, Linux, and Mac OS X.
It is compatible with all email clients using standard SMTP, POP3, or IMAP4 (including SSL/TLS variants and STARTTLS support). It is free for consumers, non-profit organizations, and the press.
Enhancements:
- This version is primarily a bugfix release, and fixes some minor issues in the 1.2.42 stable version.

[COPYRGHT=1]

You may recall that in 1997, Netscape embarked on a project to rewrite Navigator/Communicator in Java. This project (code named "Xena," but sometimes referred to by the press as "Javagator") was cancelled before completion.

Grendel is the mail-news portion of the Xena project written in Java. Its goal is to be a true cross-platform application with a feature set that satisfies the poweruser.

Grendel was originally developed as a part of the "Javagator" project at Netscape. This project was cancelled before completion after 3 years of development. After the source for Grendel was released other people started to work toward completing it for about another 2 years. The original release was therefore incomplete.

The build system is currently being redone to use Apache Ant instead of Makefiles. The easiest way to compile Grendel in its current state is to grab a copy of JCreator and create a Grendel project in the directory and compile it. A lot of test files are currently being separated out into different directories so if a certain file isnt compiling nicely, its probably because its a broken test file that can be deleted from your tree safely.

Were also in the process of moving Grendel from its own XML format to a Mozilla-friendly XUL format using the MozCreator Java XUL Parser API. Wed also like to contain all resources into one easy to manage resource folder instead of dumping them all over the source tree.

Why have Grendel when we have Thunderbird?

A primary goal with Grendel is restoring the libraries contained in the email client to full state as well as providing a working email program. Having a Java port of many of the Mozilla libraries from C++ to Java would be very valuable to many projects. The code has a lot of potential and having the Mozilla platform available for Java programmers can be a invaluable resource for Java programmers wishing to utilize email features easily. Its Java design eliminates some of the problems of a C++ design like Thunderbird. For example, Java has garbage collection and no restriction of language features in order to maintain cross-platform compatibility (like with C++ and lack of feature usage like templates for compatibility).
