At what point in processing to you want the ligths to blink? * Beginning of mail transaction? * Queue file creation? * Complete Message accepted into the incoming queue? * Message moved to the active queue? * Message delivery to each group of recipients? * Message delivered for all recipients and deleted from the queue? > Outgoing: to outside via SMTP Similar questions... The lifecycle of an email message is not a single event. If you just want server "activity" blinking lights, hook the syslog server to trigger the lights when Postfix logs something (does not really matter what). -- Viktor.
