Here’s something I stumbled on while writing my GW8 Upgrade Guide:
The new GroupWise 8 MTA opens a SOAP connection (for administrative purposes) on port 7161. If you intend to run more than one MTA on any particular server, you must set a unique SOAP port for the additional MTAs. This cannot be done in ConsoleOne, but must be configured in your MTA startup file. The default port is 7161. For each additional MTA you should set an alternative port.
- NetWare/Windows: /soapport-7162
- Linux: — soapport 7162
This is undocumented as far as I can tell.
