Is it possible that cron starts submitting the message the moment the
cron job starts (perhaps because it produces some initial output) and
only finishes submitting it when the cron job finishes some time later?

(On a quick test, this is what happens if you directly submit a local
message to Exim by using '/usr/sbin/sendmail addr' and then just letting
it sit for a while before typing the Ctrl-D to end submission and send
it. I wound up with 'QT=11m54s DT=0s', and the timestamp on the '<='
line was the point where I hit Ctrl-D.)
