Configuring the Email Engine for a server group
For a single configuration, the syntax is: Server-Group-Email-Admin-Port: 2020
If multiple s are configured for the server, each engine must have a unique RMIPort. For a multiple configuration, use semicolons to separate the RMIPort numbers: Server-Group-Email-Admin-Port: 2020;2030;2040
This enables the server to communicate email administration information to during server group processing. When multiple port numbers are specified, the server sends the same information to each port number.
