"queue_time: The amount of time the message has been in the queue on
the local host is logged as QT=<time> on delivery (=>) lines, for
example, QT=3m45s. The clock starts when Exim starts to receive the
message, so it includes reception time as well as the delivery time
for the current address. This means that it may be longer than the
difference between the arrival and delivery log line times, because
the arrival log line is not written until the message has been
successfully received."
