Once POA settings have been associated with a Post Office it is shown with a red icon in the system tree view. For example, in the figure below two Post Office objects are visible. The Post Office object labelled 1 (GWDEVPO) does not have any settings associated with it. The Post Office labelled 2 (GWDEVPO2) is shown with a red icon, indicating connection settings have been applied.
Note that specifying the direct path to the post office can result in significantly faster performance compared to specifying an IP address and port number.
