## Manually Creating a ScanMail Resource for Virtual Servers

You can install ScanMail to virtual servers on clusters during installation. Once the installation is complete, you cannot install ScanMail on more servers using the Setup program. ScanMail does not support build upgrades in the cluster environment.
If you want to add virtual servers to a cluster and have the servers protected by ScanMail after the initial installation, you must first manually create a ScanMail resource for the new virtual servers.
