En/3.2/Zentyal Unified Communications
In this section you will see the different communication services integrated in Zentyal, which enable centralised management of an organisation's communications, and allow users to work with all them using the same password.
Zentyal features an integrated mail service. It allows quick and easy integration with the user's e-mail clients, offering also spam and viruses prevention.
Since email became popular, it has suffered from unwanted mail, sent in bulk. This type of mail is often used to deceive the recipient in order to obtain money fraudulently, or simply unwanted advertising. You will also see how to filter incoming and outgoing e-mail within your network and to avoid both the reception of unwanted emails and block outgoing mail from any potentially compromised computer of your network.
OpenChange is a portable Open Source implementation of Microsoft Exchange Server and Exchange protocols, considered as core open source technology and recognized by Open Invention Network as part of the Linux System definition. Zentyal integrates OpenChange to provide a native, drop-in replacement for Microsoft Exchange Server and actively contributes to the continuous development of the OpenChange technology by developing new features, submitting bug reports and patches and by donating all the profits generated by the Zentyal book sales to the OpenChange project.
The corporate instant messaging service, based on Jabber/XMPP, is also described. This module provides an internal IM service without having to rely on external companies or an Internet connection and ensures that conversations will be kept confidential, preventing data being passed through third parties. This service provides conference rooms. It allows, through the use of any of the many available clients, to have synchronous written communication in the organisation.
