Free webmail server software for linux

Dwarf Mail Server is a full-featured mail server developed on the Java platform, implementing SMTP, POP3 and IMAP4rev1 protocols.
Dwarf Mail Server provides support for rich application message processing via pluggable mail filters and agents, as well as full handling of virtual domains for the SMTP/POP3/IMAP4 protocols, and is free of charge for the binary redistribution.
Since the server is based on the Dwarf framework, it also shares its common design principles and features - simplicity, high modularity and extensibility, authentication and authorization, XML-based configuration, logging and remote management.
Main features:
- ESMTP, POP3 and IMAP4rev1 implementation
- application logic layer provided by mail filters and agents
- virtual mail hosts in SMTP/POP3/IMAP4 server
- application-independent authentication and authorization
- sample JSP-based webmail interface
Dwarf Mail Server is targeted for both end users who are just looking for simple, secure and robust mail server as well as developers who need an extensible and powerful framework for application message processing.
For users with minimal requirements it can offer portability, simple configuration as well as strong security.
- Portability: several OS platforms are supported via the Java technology, including MS Windows, UNIX/Linux/BSD, MacOS X and others.
- Configuration: just 3 lines have to be changed to fire up a sample mail server and a few of them to run a full featured SMTP/POP3/IMAP4 server.
- Security: it uses Java Platform Security Architecture in combination with Java Authentication and Authorization Service (JAAS), as well as SSL/TLS for the secure communication.
Advanced or enterprise users can additionally appreciate performance scalability, multiple domain handling, enhanced security features and modular design easing to incorporate it to the existing infrastructure.
- Scalability: gaining from multithreaded design and dynamically adjustable allocation of resources.
- Multiple domains: server is able to handle multiple virtual domains in a single instance for all SMTP, POP and IMAP protocols.
- Enhanced security: includes subject-based permissions and access control lists for IMAP, SMTP relaying control rules, host-based filtering, SSL/TLS communication, basic anti-spam filtering, etc.
- Robustness: client/server network communication is by design separated from the resource-expensive application logic layer. The server implementation is based on the unparsed byte streams whenever possible, including its own and highly efficient MIME parser.
Dwarf Mail Server also appears to be a suitable platform for application development and customization. Its modular structure and lightweight API allows enhancing existing functionality or completely exchanging the certain part as a whole:
- Message processing: mail filters and agents provide an unique infrastructure for rich message processing.
- Mail queue: physical mail queue representation is abstracted by the API specification and may replaced by a custom implementation.
- Storage subsystem: physical data representation (i.e. messages, folders, configuration options, ACLs) is abstracted by API and may be replaced by a custom implementation based on filesystem, SQL database, etc.
- MIME parser: the parsing engine may be reimplemented for the top efficiency according to the currently used mail storage.
Dwarf Mail Sever has been tested with the most popular mail clients like MS Outlook, Mozilla, Thunderbird, Opera, Apple Mail, Becky!, Pegasus, Eudora, Pine, The Bat! and others.
Other features:
- multi-threaded server
- dynamically adjusted number of active threads
- server API for mail, user data and ACL storages
- robust SMTP server architecture with flexible queue design
- simultaneous deliveries to remote SMTP hosts
- transparent Delivery System Notification (DSN) mechanism
- support for shared mail folders
- fast and universal stream-oriented MIME parser
- runtime server configuration
- built-in SSL/TLS support
- full documentation with user guides and tutorials
- samples with source code

- pluggable services (IMAP, POP3, ...) through the Java Mail API
- configurable looknfeel through templates
- user configurable mailboxes: each folder may be on a different IMAP host
- sophisticated folder support
- support for multiple languages
- MIME support: images, html- and textfiles are shown via the webbrowser (configurable), all other files may be downloaded with a click
- fancy mail formatting: link highlighting, umlaut conversion, "smiley-substitution"
- Very fast compared to CGI scripts
- Modular concept with plugin support
- Easy administration (webinterface) and installation

Video server is a streaming video server which feeds a Java applet/application for display. The updates are rather slow, somewhere in the 10 frames/second range on a PIII. The server is written in Bigloo scheme and C. The client is written in Java.

To bring up the video server you have to do the following.

./vs --channel 25 --sd 12 --input 0

./vs --help
for more options. (This seems broken with the newest version of bigloo .... )

How to bring up a java client to connect to a server:
Insure that video/java is in your classpath, and invoke

java vpanel servername

NS WebMail project is a simple set of PERL scripts, it works using module Mail::POP3Client, and allows to send and receive MIME compliant mails.
The whole thing is "secured" using POP3 authentication, ie mail cant be send or retrieved without initial correct authentication.APOP and standard PASS authentication work.
No need of any SQL base and so on. However, better know how PERL and CGIs work ! This allows NSWM to remain simple and light, and not to require an important set of PERL modules.
NSWM now support two kinda security improvments:
- HTTP Auth: just configure your Apache to authenticate user with normal HTTP Auth. Then you
need to use indexauth.pl instead of index.html as a start page, and run NSWM in mod_perl.
It works automatically.
- Cookie stored key: the key used to encrypt the password may be stocked partially in a cookie.
This prevents bad guys from accessing other users inboxes when they used shared computers.
You have to enable this feature in the configwm.pm file, at "cookiedomain": enter your
domain to enable the feature, comment the line out to disable.
Both security features will work over HTTPS.

This way we can improve NSWM.
installation
1- Unzip it:
On performant UNIX (with recent gnu tar), do a tar xvzf nswm-XXXXXX.tar.gz
On Windows, use Winzip or PowerArchiver (http://www.powerarchiver.com)
2- Set up your favorite HTTP server to handle the application.
For Apache:
=> put an Alias section as /nswm for the nswm/html directory
=> put a ScriptAlias section as /nswm/cgi-bin for the nswm/cgi-bin directory
For IIS,NES:
Use the graphic interface to set it up properly. Refer to server documentation.
3- Then you have to edit configwm.pm file and specify your SMTP server ($SMTPserver variable).
Words and paths can be set up in config.pl file.
You can also choose the language.
Nota: configwm.pm template is configwm.pm.dist.
4- PERL Modules to install if not installed:
Dont forget to install them (example with Mail::POP3Client):
=> perl -MCPAN -e install Mail::POP3Client on UNIX (or see at http://www.cpan.org)
or ppm Mail-POP3Client on WNTs ActivePerl (but better see at http://www.activetsate.com)
The following modules/packages are needed:
IO-stringy,MIME-Base64,MIME-Lite,MIME-tools,MailTools,Mail::POP3Client,TimeDate,URI,CGI
(yeah, thats a lot, i know. MIME encoding/decoding isnt a simple thing...)
5- Misc install things:
Dont forget to chmod 777 (or, better, chown apache or nobody or www-data) the /var/opt/nswm/log and
/var/opt/nswm/tmp directories if you dont change those locations in the configwm.pm file.
You can do a small cron script to launch bin/nswmcron to enable the automatic cleanup of temp files (This is automatically done by the RPM). Dont forget to change the html/title.htm file....
Enhancements:
- Several improvements in mail header decoding in the inbox.
- Optional ability to report spam to spam software (tested and documented with SpamAssassin).
- Full management of the "Urgent header".
