However, by installing ocxQmail, you have made a smart choice, because ocxQmail scales up easily to a distributed, Enterprise solution.
If you have your eye on the future, if you have to plan for peak loads, or if you have large quantities of mail or large attachments to send now, ocxQmail is designed for you.
The architecture of ocxQmail allows multiple machines acting as
dispatchers and initiators.
An initiator is a machine that runs the ocxQmail.ocx and submits messages to a dispatcher.
A dispatcher is a machine running the NT Service that physically sends the messages.
When running ocxQmail on more than one machine, most users will start by offloading dispatching to a second machine.
NB: multiple machines will need additional licenses. See order form for details.
The NT service dispatcher component of ocxQmail can be setup on a second machine to further increase the responsiveness of your main webserver.
Version 1.1 will also allow each message to specify
the directory to which the message will be spooled. This will
allow very high volumes of messages to be sent efficiently and
quickly, by distributing the actual sending of
messages to multiple ocxQmail
dispatchers running on different machines/CPUs.
Remember that if you specify only one mail-server it may become over-extended. Specify multiple mail-servers for large quantities of emails.
The terms Initiator is equivalent to Client, Dispatcher is equivalent to Server. They are used to minimize confusion with other terms such as COM Server, client browser, client side scripting, server side scripting, Internet Information Server, web server, NT Server, etc.
