Preface About This Guide 13
 Junk mail and virus filtering. Mail service protects users from junk mail and other
annoying or unauthorized messages. You can define filters that help minimize junk
mail and viruses, filter out unsolicited commercial email, and detect messages that
contain particular content. Junk mail filtering, based on the powerful SpamAssassin,
includes an autolearning option.
 Network gateway setup. A new application, Gateway Setup Assistant, automates
the configuration of a simple gateway between the local network and the Internet.
A gateway lets you share the server’s Internet connection among computers on the
local area network (LAN). Gateway Setup Assistant configures Dynamic Host
Configuration Protocol (DHCP), Network Address Translation (NAT), firewall, DNS, and
VPN services automatically.
 Secure Sockets Layer (SSL) certificate management. Server Admin makes it easy to
manage SSL certificates that can be used by mail, web, Open Directory, and other
services that support them. You can create a self-signed certificate, and generate a
Certificate Signing Request (CSR) to obtain an SSL certificate from an issuing
authority and install the certificate.
Collaboration Services
Collaboration services promote interactions among users, facilitating teamwork and
productivity. Mac OS X Server continues to provide such collaborative support as
mailing list management, group account and folder management, and cross-platform
file sharing. Two new collaborative services have been added for version 10.4:
 Weblog service. Mac OS X Server provides a multiuser weblog server that complies
with the RSS and Atom XML standards. Weblog service supports Open Directory
authentication. For additional safety, users can access Weblog service using a website
that’s SSL enabled.
