The above logging gives you the link between client and queue ID. client = D57E1702.static.ziggozakelijk.nl[213.126.23.2] queue ID = 3ZwCmG272nz1L8Zd >From here on, the smtp daemon, cleanup daemon, queue manager, and delivery agents will show the same queue ID in status reports. You're using "long" queue IDs which never repeat (unless someone resets the clock. don't). In addition, the logging shows the process that logs the information: process name = smtpd process ID = 9220 Each process handles one or more deliveries during its life time, so the process ID (9220 above) is not unique for this particular delivery.
