Multi-Server Deployment: Three Servers
This deployment scenario applies to organizations using multiple Mail Transfer Agents (MTAs) and PureMessage servers to handle the volume of mail associated with a larger user base.
This deployment is similar to the previous example in that a single server runs the Centralized Server Manager, Database Server and End User Web Interface Server roles. In this configuration, multiple edge servers handle a higher volume of mail traffic and filtering.
You can scale PureMessage by adding more edge servers for increased capacity.
