The only thing we can match on is the PID of the 'smtp' process. In the code we asumme that the TLS log entry always happens before the actual smtp send entry that has a QID. This means we save the TLS log entry in a map with the PID as key and then, once the send entry happens, we look it up and add the log entry to the QEntry's logs.
