Free axigen mail server office edition free 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

Boston University Linux is based on Fedora Core Linux, but specifically tailored for the BU environment.

Weve added security updates, made modifications to make software work better with the way things are set up here, and added some applications that we think you might like to have.

The server edition of BU Linux provides a modern, stable, and robust server platform suitable for long-term deployment in many roles throughout the university.

Supported Hardware

Currently, only i686-class machines are supported. This includes almost everything from Intels Pentium Pro on. AMD64 and Intel EM64T systems will work fine using their 32-bit mode. Watch for a 64-bit version later this summer.

Specific Notes on Server Applications

Mail Server:

BU Linux 4.5 Server Edition (Zodiac) includes three different choices of Mail Transfer Agent (MTA) for your mail server. Each of these open source servers has its unique strengths, and you can install one or more and use the utility system-switch-mail to choose which is active.

The default is IBMs Postfix, which is designed from scratch to be secure and easily configurable. On a newly-installed BU Linux machine, Postfix is configured to exchange mail on the local machine and to send mail out to other systems, but not receive mail from the network. For this reason, outgoing mail from global BU accounts (those matching valid BU login names and with the proper UID) will appear to come from @bu.edu rather than @hostname.bu.edu. Local users (including system accounts) will retain the hostname, but without reconfiguration, any replies will bounce. Changing the system to accept mail is easy; see the BU Linux web site for details.

For the maximum flexibility and for compatibility with existing configurations (and with existing expertise), we also include the traditional standard Sendmail. And, if you have particular special needs, you may find that the new Exim MTA fits your situation best.

No matter which MTA you choose, please contact us if you need any assistance. With so many options available, the situation can be confusing, and its unfortunately easy for an accidentally misconfigured system to become a target for spam relayers. We have significant expertise at configuring both Postfix and Sendmail in a variety of situations, and will be glad to help.

FTP Server:

This release of BU Linux provides two options for FTP. The first is vsftpd, which is designed to be simple and secure. This is the most appropriate for almost all situations, but if you require more power and flexibility, we also include ProFTPd, which has many more options and a configuration syntax similar to that of the Apache web server.

Please also remember that FTP is an insecure protocol and that any passwords used travel over the network in plain text. For this reason, its best to avoid anything but anonymous FTP. For user-authenticated file transfer, use SSH and SFTP. (SFTP is provided by the OpenSSH server and enabled by default.)

Web Server:

The web server software included in BU Linux is the industry-standard Apache httpd. We also include PHP 4.3 and many other useful tools for building a web server.
If you need to provide authenticated access to web services to BU users, please contact us and we will provide you with our University-standard Weblogin module. This provides a powerful and flexible means of single-signon access control for the BU user community and we want to make it as easy as possible for you to provide this for your users.

Database Server:

BU Linux includes MySQL 4.1 and PostgreSQL 7.4. For less demanding SQL applications, we also provide SQLite 3, which provides simple SQL databases without the management overhead of running a SQL server.

SILC Server provides system administrators ability to easily and quickly set up new SILC networks. SILC Server is full implementation of server side of the SILC protocol.
SILC Server is ideal for small offices and organizations to set up secure conferencing network in LAN. SILC Server is compact and fast, and scales easily to Internet usage as well.
SILC Server provides full featured implementation of server side of the SILC protocol. The SILC Server is intended for system administrators who would like to set up either own SILC router or SILC server.
SILC Server is ideal for small offices and organizations to set up secure conferencing network in the local area network (LAN). SILC Server project is also suitable for Internet usage as it scales well, is compact and fast.
SILC Server can act either as SILC router or SILC server. It is also able to act as Backup router and take the responsibilities of the primary router if it becomes unresponsive. If your network has only one server then SILC Server acts by default as router server. Small LAN networks manage fine with only one SILC Server so it is very easy and fast to set up.
The difference of router server and normal SILC server is that router server handles most of the message routing and also keeps the global network state up to date. Normal SILC server on the other hand handles only local users and message routing to them. This arrangement makes the SILC network fast and scalable. SILC Server is easy to configure to act either as normal server or router server.
Whats New in 1.0.4 Stable Release:
- This release fixes a small problem with parsing the 1.3 protocol version string correctly.
- Clients that conform to the 1.3 protocol will not be able to connect to a SILC server that isnt running this version.
Whats New in 1.1 Beta 1 Development Release:
- Support for the new SILC Toolkit was added.

These are the primary mail utilities of the GNU system.

Specifically, this package contains a POP3 server, an IMAP4 server, and a Sieve mail filter. It also provides a POSIX mailx client and a collection of other tools.

Dwarf Server Framework is a Java technology-based framework for developing network server applications.
The primary goal of Dwarf is to support development of network servers based on the Internet standards. However, its architecture is quite universal and it is not limited to this kind of applications only.
The first available Dwarf-based applications are the Dwarf HTTP Server with Java Servlets and JSP and Dwarf Mail Server with ESMTP/POP3/IMAP4.
Simple design and very concise API together with an extensive documentation makes the learning and consequent work with the framework easy and fast for the development team.
Modular multithreaded architecture as well as efficient implementation guaranties the performance on top. Incorporation of Java 2 Platform Security Architecture and Java Authentication and Authorization Service (JAAS) helps to meet todays high security demands.
Dwarf Server Framework, although not an all-purpose universal wheel, offers extending the server functionality by customizing almost all its components:
- multithreaded service development
- support for TCP/UDP based services
- authentication via login modules
- authorization based on subjects
- logging and configuration
Furthemore, it comes with the full documentation, guides and examples, and is free of charge for the binary redistribution.

Nexedi Desktop Linux Server (DLS) is a LiveCD which instantly provides 500+ Linux Desktop applications to all PCs in a Local Area Network (LAN).

It is compatible with Windows, MacOS, Unix or GNU/Linux environments as well as with eBox thin clients. Nexedi DLS also includes a complete network infrastructure solution (file server, mail server, collaboration server, directory service, etc.) based on modern protocols (ex. LDAP, Samba 3, IMAP, etc.).

Nexedi DLS Live CD allows small and medium size organisations to implement a high end Linux desktop and network infrastructure solution in one minute.

Nexedi DLS is a LiveCD: it requires no installation. Simply insert the LiveCD in any PC, turn on the PC and choose the boot from CD option.

After about one minute, a complete Mandrakelinux server is ready to serve thin clients and provide file sharing, directory, messaging and collaboration services to your entire network. Enter your network information through a simple web based interface.

You can now access all Nexedi Desktop Linux Server features from any other PC in the same local network.

Nexedi DLS LiveCD can be used from any standard PC based on x86 architecture (Pentium, Athlon, Opteron, etc.). 512 MB RAM is recommended to serve a few users. 1024 MB and a fast CPU (Pentium IV, Pentium M, Athlon, Opteron, etc.) is recommended to server 10 simultaneous users.

Applications:

Nexedi DLS applications are multiple. Some applications are based on DLS acting as a complement to existing infrastructure. Other applications are based on DLS acting as a replacement to existing infrastructure.

* Office and Productivity:many Mandrakelinux applications can be very useful as a complement to existing Windows or Macintosh environments. Installing a single DLS server allows in a network allows everyone to access those applications without requiring any complex software installation or setup.
* Internet Security:by placing a DLS server in the DMZ of an organisation, it is possible to protect all PCs in a local network from viruses or spyware. Internet applications are launched on the DLS server and accessed by users through tightVNC from Windows or Macintosh PCs. Internet attacks might compromise the DLS server but will not be able to access sensitive data on users PCs. This architecture is similar to having two physical networks, one for internal uses, one for internet access, but at a much lower cost.
* Software Development Box:a single DLS server can be used as a shared multi-platform software development by Windows or Macintosh users. Mandrakelinux includes many advanced integrated development environments (IDE) which can be used to produce GUI, Web or embedded applications.
* Network Administration Box:a single DLS server can be used as a shared network administration environment. Mandrakelinux includes many advanced and free network administration tools.
* Thin Client Server:Nexedi DLS is a multi-protocol thin client server and gateway. A typical DLS server can handle 10 simultaneous sessions. Thin clients can use the VNC, tightVNC or XDMCP protocols to access a complete desktop session. Any DLS session can access other thin client protocols (RDP, X11, NX, etc.). Nexedi DLS also includes various emulators and virtualizers which allow to run Windows and Macintosh applications directly.

Mail::Bulkmail::Server is a Perl module that handles server connections and communication for Mail::Bulkmail.

SYNOPSIS

my $server = Mail::Bulkmail::Server->new(
Smtp => your.smtp.com,
Port => 25
) || die Mail::Bulkmail::Server->error();

#connect to the SMTP relay
$server->connect || die $server->error();

#talk to the server
my $response = $server->talk_and_respond("RSET");

Mail::Bulkmail::Server now handles server connections. Mail::Bulkmail 1.x and 2.x had all the server functionality built into the module itself. That was nice in terms of simplicity - one module, one connection, one server, and so on. But it had some downsides. For one thing, it only allowed for one connection. And since I wanted to allow multiple server connections in 3.00, that had to go. For another, it was a pain in the butt to change the server implementation. This way, you can easily write your own server class, drop it in here, and be off to the races.

For example, the Mail::Bulkmail::DummyServer module for debugging purposes.
This is not a module that youll really need to access directly, since it is accessed internally by Mail::Bulkmail when it is needed. Specify the data you need in the conf file and the server_file attribute, and you wont ever need to touch this directly.
