SMTP services are used by K2 blackpearl to send e-mail notifications. Any compatible mail server is supported, such as Windows SMTP, Exchange Server, or third-party SMTP servers that can be installed on Windows Server 2008 or later. A message queuing service is required for the K2 blackpearl Event Bus Server (K2 blackpearl supports Microsoft Message queuing out of the box). The Event Bus Server is used to watch events and send notifications on certain conditions and thresholds, providing a mechanism for reporting business activity and gathering key performance indicators (KPIs) based on current conditions in the business environment.
