Free axigen mail 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

NNML::Server is a minimal NNTP server.

SYNOPSIS

perl -MNNML::Server -e server
perl -MNNML::Server -e unspool

NNML::Server server implements a minimal NNTP server. It is (hope-) fully conformant to rfc977. In addition the commands XOVER and AUTHINFO are implemented.

Supported commands:

ARTICLE, AUTHINFO, BODY, GROUP, HEAD, HELP, IHAVE, LAST, LIST,
MODE, NEWGROUPS, NEWNEWS, NEXT, POST, QUIT, SLAVE, STAT

XOVER, XHDR, LIST NEWSGROUPS ng-spec

The main reason for writing this was to synchronize my mail directories across different hosts. The Mail directories are MH-Style with a .overview file in each folder and an active file in the base directory. These are maintained by the Emacs Gnus backend NNML. To get started, you can generate/update this files using the overview program. Upon POST and IHAVE commands this files will also be updated.

To start from scratch use:

touch /tmp/active;
perl -MNNML::Server -e server(base => "/tmp", port => 3000)

To export your mh-Mail use:

perl overview -base ~/Mail
perl -MNNML::Server -e server(base => "$ENV{HOME}/Mail", port => 3000)

The command POST and IHAVE honour the Newsgroups header if not overwritten by the X-Nnml-Groups header. Articles will contain an appropriate X-Nnml-Groups header when retrieved by message-id.

When the client submits the SLAVE command, all forther post requests are spooled in $Config-spool> (usually ~/Mail/NNML.spool) for performance reasons. You can process the spooled articles by submitting the XUNSPOOL command or by calling

perl -MNNML::Server -e unspool

Rejected articles will be saven in $Config-bad> (usually ~/Mail/NNML.bad)

Mail::Sendmail is a simple platform independent mailer.
SYNOPSIS
use Mail::Sendmail;
%mail = ( To => you@there.com,
From => me@here.com,
Message => "This is a very short message"
);
sendmail(%mail) or die $Mail::Sendmail::error;
print "OK. Log says:n", $Mail::Sendmail::log;
Simple platform independent e-mail from your perl script. Only requires Perl 5 and a network connection.
Mail::Sendmail contains mainly &sendmail, which takes a hash with the message to send and sends it. It is intended to be very easy to setup and use.
Main features:
- Automatic time zone detection, Date: header, MIME quoted-printable encoding (if MIME::QuotedPrint installed), all of which can be overridden.
- Bcc: and Cc: support.
- Allows real names in From:, To: and Cc: fields
- Doesnt send an X-Mailer: header (unless you do), and allows you to send any header(s) you want.
- Configurable retries and use of alternate servers if your mail server is down
- Good plain text error reporting
Version restrictions:
- Headers are not encoded, even if they have accented characters.
- No suport for the SMTP AUTH extension.
- Since the whole message is in memory, its not suitable for sending very big attached files.
- The SMTP server has to be set manually in Sendmail.pm or in your script, unless you have a mail server on localhost.
- Doesnt work on OpenVMS, I was told. Cannot test this myself.

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.

Twisted Mail project provides client and server implementations of SMTP, POP3, and IMAP4.
These differentiate themselves from the Python standard library implementations both by presenting a much higher-level, easy-to-use interface and in their server components, which allow the implementation of custom servers for each protocol without dealing with protocol-level issues.
Twisted Mail includes a simple demonstration email server which accepts messages over SMTP, stores them in a Maildir arrangement, and can serve them to clients over POP3.
Enhancements:
- The IMAP4 client now properly quotes usernames and passwords when necessary.
- It also handles unsolicited FLAGS responses.
- The IMAP4 server can now parse multiple literals in a single command and to FETCH requests with multiple BODY parts.
- A bug where Deferreds returned from IMAP4 client methods would not receive connection lost notification has been fixed.
- Startup time on OS X has been improved.
- The SMTP server has been sped up.
- The POP3 mailbox API has been expanded to allow Deferreds to be returned in some cases.
