Intentionally place all incoming email as 'held'
What would be the easiest way to set up zimbra so that for a period of time during the day (say an hour) all incoming mail would be received by Zimbra MTA but not dispatched to the relevant user@domain inbox?
We could use postsuper -H ALL but it would have to be run every second (literally) to hold all email for the time period, right?
Ideally a user would still have inbox access and be able to send email (although maybe not) but just not receive anything. After an hour, the queue is cleared (using postsuper?) and all is well.
