System information

17Chapter 1 Introducing Mac OS X Server
Users can view and add contact information in a server-based address book by using
the Address Book application on any Mac with Snow Leopard. Address Book Server can
also allow Snow Leopard users to nd public contact information in directory servers
that your server is connected to. Users of other computers can access address books on
your server using third-party applications that are compatible with the CardDAV open
standard.
Mail Server
Snow Leopard Server boosts its Mail Server performance, reliability, and scalability with
a new, open standards–based engine designed to handle thousands of simultaneous
connections. In addition, Mail Server is enhanced to include push email, server-side
email rules, and vacation messages.
Mobile Access Server
Snow Leopard Server has a Mobile Access Server that can give mobile users secure
access to your private services without inconvenient VPN connections. You specify
whether users can access private mail, web, iCal, and address book services. Users
connect to the reverse proxy Mobile Access Server on the Internet, and it makes secure
connections on their behalf to services that Mac OS X Server provides on your private
network.
