M
mail host The computer that provides your mail service.
managed client A user, group, or computer whose access privileges and/or preferences
are under administrative control.
managed preferences System or application preferences that are under administrative
control. Server Manager allows administrators to control settings for certain system
preferences for Mac OS X managed clients. Macintosh Manager allows administrators to

MBONE (multicast backbone) A virtual network that supports IP multicasting. An
MBONE network uses the same physical media as the Internet, but is designed to repackage
multicast data packets so they appear to be unicast data packets.
MIBS (management information bases) Virtual databases that allow various devices to
be monitored using SNMP applications.
MIME (Multipurpose Internet Mail Extension) An Internet standard for specifying
what happens when a Web browser requests a file with certain characteristics. A file’s suffix
describes the type of file it is. You determine how you want the server to respond when it
receives files with certain suffixes. Each suffix and its associated response make up a MIME
type mapping.
MTA (mail transfer agent) A mail service that sends outgoing mail, receives incoming
mail for local recipients, and forwards incoming mail of nonlocal recipients to other MTAs.
multihoming
The ability to support multiple network connections. When more than one
connection is available, Mac OS X selects the best connection according to the order
specified in Network preferences.
MX record (mail exchange record) An entry in a DNS table that specifies which
computer manages mail for an Internet domain. When a mail server has mail to deliver to an
Internet domain, the mail server requests the MX record for the domain. The server sends
the mail to the computer specified in the MX record.
N
name server See DNS (Domain Name System).
NetBIOS (Network Basic Input/Output System) A program that allows applications
on different computers to communicate within a local area network.
NetBoot server
A Mac OS X server on which you have installed NetBoot software and
have configured to allow clients to start up from disk images on the server.
