Before you add an appliance to the Email module, you should have already executed the Websense® appliance firstboot script to activate email security functions on the appliance and configured network interfaces in the V-Series Appliance manager or X-Series command-line interface (CLI). Interface information includes IP address, subnet mask, default gateway, and up to 3 DNS server IP addresses. See Websense V-Series Appliance Getting Started or the X-Series Appliance Getting Started for more details about setting up and configuring an appliance.

TRITON AP-EMAIL may also be deployed as a virtual appliance using a VMware platform (ESXi v4.0 or later). See the virtual appliance Quick Start Guide for complete information about deploying and configuring a virtual appliance.

If you change either the appliance hostname or communication IP address on the appliance, you must make the same change in the Settings > General > Email Appliances page. The Email module does not detect this change automatically.

Email traffic is usually routed through dedicated appliance interfaces (E1/E2). However, if you want to route traffic through the C interface (for example, to transfer log data to a SIEM server), you need to define a route on the V-Series Appliance Manager Configuration > Routing page or use the X-Series CLI. You should note that you need to stop and restart email security services on the appliance each time you add or delete a route on the appliance.
