We are using Exchange server for emails. We are having problems sending SMTP email. We can receive emails. When we sending external emails a error appears in the SMTP mapping log as below:
07/06/04 18:45:50 210.49.226.133 Guest 0000400745 Requested: TCPMapping: Connected to 192.168.1.2:25

07/06/04 18:45:57 192.168.1.2 Guest 0000400736 Terminated exit code 2
Does anyone have any idea why this is occurring?
