One of our users has a daily cron job which runs for 24 hours. The output is emailed to the user in the usual way. Because the output is piped into sendmail (postfix) over 24 hours, it appears in the queue with a pre-qmgr delay of ~86400 seconds. Our monitoring system then flags an alert as it thinks there's a delivery issue.
Is there any way of preventing this behaviour? Is there any way of getting sendmail to "start the clock" once the inbound pipe from cron has finished?
