Microsoft Exchange Mail-On-Demand
Microsoft Exchange Server is an e-mail server
that can be used to handle local (Intranet) e-mail. It can also be configured to send and
receive outgoing (Internet) mail on demand (dial on demand). Not only can Exchange Server be used
as a local mail server to handle your intranet mail, but it can also be configured to send and
receive mail to and from the Internet.
With the Exchange Server, you can have the server dial-up to your local ISP on demand, then
connect to the mail service on your Virtual Private Server and download any stored mail. This
allows you the ability to have continuous e-mail support on your local intranet where traffic is
heavier, in addition to being able to send and receive e-mail to and from the Internet on a more
periodic basis. You should be aware that we do not currently have a solution for Exchange Server
for Virtual Subhosts.
Because your Virtual Private Server is always connected to the Internet, it is always
available for incoming mail messages and can store (or queue) these messages for you until you
are ready to retrieve them. The ability of the Exchange Server to perform dial-on-demand e-mail
retrieval allows you to take advantage of the lower prices of a dial-up connection, providing a
more affordable Internet mail solution for your company. The information provided here should be
easily adaptable for any other Mail Server, such as Novell's Workgroup Server.
The following diagram illustrates the theory behind the process. You and your fellow employees
are located on your LAN or Intranet at your Office. You use a dial-up connection through your
ISP to surf the web, read news, download files, and remotely administrate your Virtual Private
Server. You may have previously had both an internal LAN mailbox and a POP or IMAP mailbox on
your Virtual Private Server.
Using the Exchange Server (or equivalent software) you can now queue your Internet mail on
your Virtual Private Server and instruct Exchange Server to periodically connect to the Internet,
download the mail from your Virtual Private Server, and then distribute it to your local area
network mailboxes.
Configuration
You need to configure both your Exchange Server and your Virtual Private Servers in order to
implement Mail-On-Demand.
