Free webmail software software for linux

PHPwebmail is a Web-based IMAP and SMTP mail client. Often it is not possible to make outside mail connections from networks behind strict firewalls, or to configure a regular mail client (for example in an Internet cafe).

With PHPwebmail a mail client only needs a WWW connection to the mailserver. Specifically it only needs a connection to the webserver hosting PHPwebmail.

Most of the times the Web and mail server will be the same machine but PHPwebmail can connect to other mailservers as well as long as an IMAP connection between these two machines is allowed.

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.
Supported languages
Modules exists and languages have been tested for:
- English (lang-en.pl module, core module)
- Francais (lang-fr.pl module, dev module)
- Russian (lang-ru.pl module, dev module)
- Hrvatski (lang-hr.pl module, trn module from dpavlin at rot13.org)
- Deutsch (lang-de.pl module, trn module from Tobias.Mueller at stud.uni-hannover.de)
- Norwegian (lang-no.pl module, trn module from erlingp at f00bar.fagmed.uit.no)

Anyone translating the langpack in another language is asked to send it us, please !
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".

Yukatan Webmail provides an advanced email management system.
The goal of the project is to create an advanced webmail system, that uses a relational database backend to provide efficient search and classification capabilities.
The project is currently in pre-alpha state. The underlying data model has just reached 1.0 status, and a couple of utility tools are under active development.
Yukatan components
The Yukatan webmail system is developed as a collection of independent components based on a central data model.
Enhancements:
- Yukatan data model 1.0
- Java importer sources
- Initial webapp code for the webmail part

zeMail is a minimalist webmail package written in Mason. It implements the basic features one would expect from an IMAP mail client, displaying folder and message contents, handling attachments and allowing you to move, mark and purge your messages.
zeMail package is written in plain HTML, and uses JavaScript only to reduce the click count, it will work perfectly with scripting disabled. Compared to the modern AJAX trend, this web mail package is designed to work everywhere.
Installation:
Download and unpack the tarball. Copy the directory lib/Zentus into your Perl inc. path (/usr/local/lib/perl/5.8.4 on Debian).
Copy the contents of mason/ into the desired subdirectory of your Apache htdocs directory or virtual host. Then add the following to your httpd.conf:
PerlModule Zentus::Mail::Connection
PerlModule Zentus::Mail::AttachmentHandler
PerlModule HTML::Mason::ApacheHandler
PerlModule Apache::Session::File
PerlModule Text::Autoformat
< Location / >
SetHandler perl-script
PerlHandler HTML::Mason::ApacheHandler
DirectoryIndex folder
< /Location >
< Location /attachment >
SetHandler perl-script
PerlHandler Zentus::Mail::AttachmentHandler
< /Location >
< LocationMatch "(/icons|/images|.ico|.html|.txt)" >
SetHandler default-handler
< /Location >
< LocationMatch "(autohandler|dhandler|.inc)" >
SetHandler None
< /Location >
This code segment can be added as-is if you intend to devote a VirtualHost to zeMail, otherwise prefix a directory name in the < Location > and < LocationMatch > tags.
Now install the necessary Perl modules from CPAN:
cpan -i HTML::Mason # or deb: libhtml-mason-perl
cpan -i Apache::Session # or deb: libapache-session-perl
cpan -i DB_File::Lock # or deb: libdb-file-lock-perl
cpan -i Text::Autoformat # or deb: libtext-autoformat-perl
cpan -i HTML::FormatText # or deb: libhtml-format-perl
cpan -i Net::IMAP::Simple # (needed really in name only,
# to be removed in next release)
You may have to create the temporary directory manually:
mkdir /tmp/zemail
chown www /tmp/zemail
Now restart your Apache and your are good to go.
Enhancements:
- Supports all basic forms of email, strips out MIME, displays attached images inline, and lets you download the rest.

Postaci (Turkish word for Postman) is a multiplatform PHP webmail software which is database independent, IMAP/POP3, multilanguage(32 languages) and fully MIME compatible. While using POP3 mode to fetch messages it uses database fields to simulate IMAP folders, on which you can save, move, delete,read e-mail.
It is a easy to set up, really secure environment and been downloaded by more than hundred thousand users all around the world. It also is bundled with a simple adressbook, a notebook, a bookmark manager application.
Postaci includes multidomain(virtual) support. Domains are stored in a DB table and all users must be linked to a domain. It can be done at tblDomains and tblUsers tables at the database. If you have a single domain on your server you won t need to do this. There must be at least one domain at the database and its index should be 1. This is the default domain for any user. You can change your default domain at the tblDomain.sql file at the queries folder.
Enhancements:
- SMTP authentication for those who need to authenticate to send email.
- An Email Address field in Preferences allows you to manually set your From: email address.
- A problem in moving messages when using IMAP has been fixed.

WizMail is a Webmail system that strives to keep synchronized with the email on a POP3 server so that it can be accessed from the Web when an email client cant be used, and then downloaded when possible.

It is also able to filter incoming email into different folders, offers different configurable identities and signatures per user, and supports drag and drop.

WizMail project supports downloading and relaying of email using any SMTP/POP3 client: using WizMailTunnel, your email server can be accessed through HTTP/HTTPS proxies.
