The Outbound Enabler (RSOE) runs as an SAP Mobile Server process and manages communication between the SAP Mobile Server and a Relay Server.
Each RSOE maintains connections to each Relay Server in a Relay Server farm. The RSOE passes client requests to the SAP Mobile Server on its Replication or Messaging port. The SAP Mobile Server sends its response to the RSOE, which forwards it to the Relay Server, to be passed to the client.
As an SAP Mobile Server process, the RSOE always starts when SAP Mobile Server starts. SAP Mobile Server monitors the process to ensure it is available. If an RSOE fails for any reason, SAP Mobile Server restarts it automatically.
