Shared Network Paths
Enable Shared Network Path editing (required if this is the first node of a cluster)
Use the options on this screen to set the shared network paths that will be used by the MDaemon cluster. This is required on the first node of the cluster so that the shared network paths can be replicated on the other nodes.
Set all network paths using a common MDaemon Network Share
Choose this option if you wish to locate all of the shared network paths under a single, common network share. This option results in all of the paths being set to the default values, and all path controls will be read-only.
Set all network paths individually
Choose this option if you wish to set each shared network path individually. Such as, for example, if you wish to store mail folders and mail archives at different network locations.
Enable Multi-Node Mail Routing
Use Multi-Node Mail Routing if you wish to share mail queues between the cluster nodes. Having multiple servers process and deliver the messages allows them to split the work more evenly and prevents messages from being stuck in the queues of any servers that are down.
