TWIG: Web-based email, contact manager and general groupware.

TWIG Groupware

TWIG is a powerful browser-independent, web-based intranet/groupware tool to access or share almost any kind of information, without the complexity or costs of other intranet/groupware packages. Features include:

One of its most common uses is as a powerful web-based email platform. You can use it to provide email accounts that are easily accessible from anywhere on the Web.

TWIG is implemented using PHP, an HTML-embedded scripting language, and the MySQL database application.

Installation
Connect to your Virtual Server via Telnet or SSH.

Install MySQL on your FreeBSD-based Virtual Server.
Install PHP4 on your Virtual Server. TWIG requires the following PHP4 dynamic module:

MYSQL, MCRYPT, FTP, IMAP

% vinstall php4-dso
Install the TWIG software by running the following commands:

Reading email
After TWIG is properly installed and configured, you will be able to read your email with any web browser (e.g. Netscape or MSIE). You simply need to access a URL like this:

http://YOUR-DOMAIN.COM/twig/

TWIG will prompt you for your email username and password. After successful authentication, the contents of your mailbox will be displayed.

NOTE: Since TWIG uses IMAP it also can be used to create additional mail folders to sort and store incoming mail. Any additional mail folders that a user creates will be created in the user's home directory as listed in your local password file (~/etc/passwd). If the user's home directory happens to be defined as a directory in the ~/www/htdocs/ or ~/www/vhosts directory structure (typically created in this fashion such that the user can upload and download content to and from a Virtual Subhost via FTP) then any mail folders these users create using TWIG will be accessible to anyone via a web client.

Therefore, it is highly recommended that these users create any additional mail folders under a Mail subdirectory and create a .htaccess file and store it in such a Mail directory to protect the confidentiality of the mail stored therein. The contents of a suitable .htaccess file are shown below:

<Limit GET POST PUT DELETE>
deny from all
</Limit>
