Alternative title: How to delay a mail queue in postfix for a certain user.
I am planning to build a solution. At first it would be I would create a separate email address for queuing. Use a client to send the email from that address. The queue on that email would be paused (not processing) and then create a job/script or something(separate question) to relay a
sendmail -q to postfix to release the queue.
How do I make the queue stay in a delayed state so this is possible. I do not wish to stop the service and restart it at certain times since that would disable all other email.
