The following describes one possibility for configuring PureMessage using the Custom Install option. See
"Server Deployment Options" for other examples.
In this installation, the first server hosts the Centralized Server Manager role, the
Database Server role and the End User Web Interface Server role. The second
server hosts both the Mail Transfer Agent role and the Mail Filter role.
Important:
- It is recommended that you install the Mail Transfer Agent role on both the central
server and the edge server that you plan to use as your mail server (as described in this
example). If you intend to install the Mail Transfer Agent role on a server that is
separate from the one on which the Centralized Server Manager role is installed, you
must specify the hostname and port number of the mail server so that the central server will
be able to send it administrative notifications and messages that are released from the
quarantine. You will be prompted to provide the hostname and port as one of the Custom
Installation steps.
- If you have the Mail Transfer Agent role (Postfix) installed on the same server as
the Centralized Server Manager role, subsequent MTA role installation on different
servers will inherit Mail Transfer Agent (Postfix) configuration from that
Centralized Server Manager when you connect with it during the installation process.
The installation wizard will not prompt you for Postfix configuration. If required, you can
change your Postfix configuration by editing related configuration files (main.cf) after
installation.
- To ensure consistent reporting across multiple servers, use ntp synchronization with ntpd
so that the system clock is the same on all servers. In addition, all servers must be set to
the same time zone for accurate reporting.
- It is recommended that you specify the same username for the PureMessage user ('pmx6' by default) on each server in your
deployment. If you use different usernames, you must manually configure the DSN string.
To install this multi-server configuration, complete the steps in the order described
below.
