Abstract
An email gateway collects, stores and forwards messages to a primary domain
server. A gateway typically has no individual accounts. Email gateways can help
both large and small enterprises solve some of the problems inherit to Internet
email services. For a small organization, a gateway can make a private email
domain affordable. This is because a service provider supplies the gateway at a
reasonable cost by sharing the hardware and software with other smaller
ventures. The primary domains in such cases can have either permanent or
dialup connections to the Internet. Larger establishments can employ securityhardened
gateways to provide protection and content filtering for their more
vulnerable enterprise email systems. Gateways can also be configured to supply
automatic realtime mail storage backup when a primary domain goes offline for
any reason. One copy of MDaemon can simultaneously operate gateways for
dozens of email domains, even while running a primary domain server of its own.

movement of traffic. The gate
at the concert hall slows the
inflow of the crowd for the
ticket taker. The amusement
park gateway limits the number
of people who can get on a
ride. In theory, gateways may
sound like restrictive devices,
but in practice, they improve
the quality of life. In or out, a
gateway regulates clutter.
Digital Gateways

Internet or some other large system. The gateway shares its connection with
