I am deploying a new zimbra Open source server for my company. A strange request came down from the CEO. He would like to disable email access on tuesday and thursday between 1100am and 300pm.
short of just shutting down the servers, what would be a good way to accomplish this. Of course emails sent to us during that period should still be delievered to mailboxes, but users should not be able to login to check either from thier office, or mobile devices/external locations
