EAS proxy usage scenarios

You use IBM Notes Traveler (formerly IBM Lotus Notes Traveler) for non-iOS devices

The internal EAS proxy is not suitable for this scenario because it only supports the ActiveSync protocol, which is used by Microsoft Exchange and by IBM Notes Traveler for iPhones and iPads. IBM Notes Traveler for non-iOS devices (for example, Android) uses a different protocol that is supported by the standalone EAS proxy.

For non-iOS devices, dedicated Traveler client software is required. This software is available through <traveler-server>/servlet/traveler or the Traveler file system. The Install App and Uninstall App features of Sophos Mobile can be used to install and uninstall the Traveler client software. Configuration has to be performed manually.

You want to support multiple backend servers

With the standalone EAS proxy you can set up multiple instances of backend email systems. Each instance needs an incoming TCP port. Each port can connect to a different backend. You need one URL per EAS proxy instance.

You want to set up load balancing for EAS

You can set up standalone EAS proxy instances on several computers and then use a load balancer to distribute the client requests among them.

For this scenario an existing load balancer for HTTP is required.

You want to use client certificate based authentication

For this scenario an existing PKI is required and the public part of the CA certificate has to be set in the EAS proxy.

You need to manage more than 500 devices

For performance reasons, we recommend you use the standalone EAS proxy server instead of the internal version when email traffic for more than 500 client devices must be managed.
