<h2>General</h2>

Kolab is a secure, scalable and reliable groupware server.
It is formed by a number of well-known and proven components
or the standards tasks such as E-Mail, Directory Service and Web Service.

<p>
Kolab adds intelligent interaction between the components,
a web administration interface, management of free-busy lists
etc.

<p>
<a href="about-kolab-clients.html">Various clients</a> can
access Kolab, among them Kontact (KDE), Outlook (Windows) and Horde (Web).

<h2>Major Features</h2>

<ul>
<li> A web administration interface
<li> A shared address book with provision for mailbox users as well as contacts
<li> POP3 as well as IMAP4(rev1) access to mail
<li> Client-side full support of S/MIME
     E-Mail encryption possible (officially Sphinx-interoperable).
</ul>

<h2>Major Components</h2>

<h3><a href="http://www.openldap.org/">OpenLDAP</a></h3>

<a href="http://www.openldap.org/"><img border="0" alt="Powered by OpenLDAP"

LDAP is used as the cornerstone for Kolab. All authentication, be it
the web admin interface or POP3/IMAP mailbox access are using LDAP as
the password store through SASL. Key configuration parameters are also
stored in LDAP and automatically applied to configuration files after a
change occurs. When you create a new user in LDAP, the Cyrus mailbox is
automatically generated for you.

<h2><a href="http://www.postfix.org/">Postfix</a></h2>

<a href="http://www.postfix.org/"><img border="0" alt="Powered by Postfix"
  src="images/postfix-logo.png" align="right"></a>

Postfix is the mail transfer agent (MTA) for Kolab server.
Postfix is easy to configure and has a Sendmail
compatibility interface for administrators who are familiar to Sendmail.

<h2><a href="http://asg.web.cmu.edu/cyrus/">Cyrus IMAP</a></h2>

Cyrus provides IMAP as well as POP3 access to user mailboxes.
It supports key features such as ACL (Access Control Lists)
that allows more than one user to share mailboxes and folders.
It also supports the Sieve mail processing language which
allows Auto Actions such as Auto-Forward and Auto-Reply on
mailboxes. Cyrus is also highly scalable.

<h2><a href="http://www.apache.org/">Apache</a></h2>

<a href="http://www.apache.org/"><img border="0" alt="Powered by Apache"
  src="images/apache-logo.png" align="right"></a>

Apache is used for the web administration interface as well
as to provide WEBDAV access to Free/Busy information for the mail
clients. It is planned that Kolab will be using Apache and PHP
to provide webmail access with groupware functionality.

<h2><a href="http://www.proftpd.org/">ProFTPd</a></h2>

<a href="http://www.proftpd.org/"><img border="0" alt="Powered by ProFTPd"
  src="images/proftpd-logo.png" align="right"></a>

ProFTPd is used by legacy clients to upload Free/Busy information
to the Kolab server.

<h2><a href="http://asg.web.cmu.edu/sasl/">SASL</a></h2>

SASL (the Simple Authentication and Security Layer) is used by all
the components and uses OpenLDAP as the store for Authentication information.
