Free mail server software for linux

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)

The Cyrus IMAP server is generally intended to be run on sealed systems, where normal users are not permitted to log in.

Electronic mail is a major infrastructure service of almost all organizations. At Carnegie Mellon the use of electronic mail has overshadowed the use of all other distributed services since the early 1990s. It is a core part of the business process of most departments. The universal availability of the Andrew Mail and Bulletin Board System (AMS) has helped a great deal to create this situation. Departments without AMS have run their own mail systems and see heavy use, as well. With the end of the lifetime of the AMS in sight, Project Cyrus began to build a new campus mail system.

The Cyrus Electronic Mail Project is continuing to build a highly scalable enterprise mail system designed for use in a small to large enterprise environments using standards based technologies. The Cyrus technologies will scale from independent use in small departments to a system centrally managed in a large enterprise.

Visitors to this site may want to also view The Cyrus Wiki, which is likely to be updated more frequently.

This document gives an overview of the Cyrus IMAP server. The Cyrus IMAP (Internet Message Access Protocol) server provides access to personal mail and system-wide bulletin boards through the IMAP protocol. The Cyrus IMAP server is a scalable enterprise mail system designed for use from small to large enterprise environments using standards-based technologies.

A full Cyrus IMAP implementation allows a seamless mail and bulletin board environment to be set up across multiple servers. It differs from other IMAP server implementations in that it is run on "sealed" servers, where users are not normally permitted to log in. The mailbox database is stored in parts of the filesystem that are private to the Cyrus IMAP system. All user access to mail is through software that is using the IMAP, POP3, or KPOP protocols.

The private mailbox database design gives the server large advantages in efficiency, scalability, and administratability. Multiple concurrent read/write connections to the same mailbox are permitted. The server supports access control lists on mailboxes and storage quotas on mailbox hierarchies.

Mail::SendEasy can send plain/html e-mails through SMTP servers (platform independent). Supports SMTP authentication and attachments.

This modules will send in a easy way e-mails, and doesnt have dependencies. Soo, you dont need to install libnet.
It supports SMTP authentication and attachments.

USAGE:

OO

use Mail::SendEasy ;

my $mail = new Mail::SendEasy(
smtp => localhost ,
user => foo ,
pass => 123 ,
) ;

my $status = $mail->send(
from => sender@foo.com ,
from_title => Foo Name ,
reply => re@foo.com ,
error => error@foo.com ,
to => recp@domain.foo ,
cc => recpcopy@domain.foo ,
subject => "MAIL Test" ,
msg => "The Plain Msg..." ,
html => "The HTML Msg..." ,
msgid => "0101" ,
) ;

if (!$status) { print $mail->error ;}

STRUCTURED

use Mail::SendEasy ;

my $status = Mail::SendEasy::send(

if (!$status) { Mail::SendEasy::error ;}

XCmail is a MIME and multi POP3 server capable mailtool for X11 using the Xclasses layout library. XCmail was designed completely object orientated and by this may be improved easily.
The main purpose of XCmail is to read and write mails which may have any kind of data added (attached). For this XCmail can handle MIME types and has so called "helpers" to show different types. And XCmail offers "encoders" which encode and decode binary data into ASCII to allow the transport as mail over the Internet.
The GUI (graphical user interface) was designed to be mostly self explaining but of course there may be some things which are not explaining them self like settings or standard names that are unknown to first users.
The GUI was designed to be as simple as it can be and self explaining. Though, there are a few buttons which are not so easy to understand fo first users because are not standard.
XCmail also offers "encoders" which encode and decode binary data into ASCII to allow the transport via mail over the Internet.
The program works with a local mailbox (eg. /var/spool/mail) and multiple POP3 servers. With POP3 XCmail uses the faster UIDL function of POP3 servers (may be disabled if servers dont support this) and has a so called "UIDL history": If you get mails from your POP3 server but dont want to remove them there and later remove them only locally other mailers will read this mails again. Not XCmail! The UIDL history keeps a history of the mails read from the server so it wont read them again.
XCmail supports multiple mailboxes, has an address book for your favority email addresses and XCmail may start external programs to encode mails or handle MIME types.
XCmail also supportes PGP within PGP MIME (RFC 2015)!
Main features:
- allows the user to add multiple parts on one mail, eg. send files together with a text (called attachment)
- get mails from multiple remote mail servers
- send mails to a remote mail server using simple message transfer protokol (SMTP)
- authenticate on SMTP servers - is sometimes required on SMTP servers to stop spammers from relaying
- authenticate at POP3 server before sending mails via SMTP - this is required by some mail servers if they dont offer SMTP AUTH
- encrypt mails so unwanted persons can not read them
- encrypt complete MIME mails - including the attachments. This is a standard specified in RFC 2015
- send a nice and small picture of yourself with any mail - this is shown if the mail is read
- speedup for POP3
- this avoids XCmail from reading the same mails multiple times from the mail server
- to send files (eg. binaries) with a mail they must be encoded - XCmail offers various encoders, from standard uuencode and base64 to Mac HQX
- because not all attached files are programs XCmail offers an open interface to handle those data - eg. open an external viewer for pictures
- with plugins XCmail may be tuned - eg. some encoders and helpers are plugins so they may not be installed if a users doesnt need them - this required less space on disk and memory
- ever send a mail and later seen that it had some words misspelled? With ISpell this is no longer a problem. ISpell offers checks in many langauges!
- Put extra headers in every mail you send, eg some more information on you or some extra settings for mail agents
- put your favorite recipients in XCmails addressbook
- keeps an second internal addressbook for faster choosing an email recipient
- searches your addressbooks for a matching name or address during you type the recipient
- group different folder to one visible vfolder - for better overview
- Dont understand the language of a mail? XCmail may translate it for you by using altavistas babelfish service!
- You want to archiv many or every mail? This takes a lot of disk space?! Use XCmails folder archiv which compresses archived folders using GZIP standard
- sort or remove your mails before you "must" read them
- put are your favorite addresses in the addressbook
- dont know how to translate a word? use the dictionarys in the Web within the XCmail GUI
- using Spam Bouncer as spam filter plugin
- delete selected mails from your POP3 server
- big mails can be transfered explicitely from your POP3 server
- vCards can be read and a personal or official (from your job) vCard can be sent with every mail (you may choose which of them)
- mails of the incoming folder may be moved to a received folder automatically by many options (after reading, replying, forwarding a mail or if it is some days old)
- helps first time users to setup XCmail
