Zimbra have released a security patch which we will be applying this evening.
Applying the patch will mean intermittent access during the first hour of the maintenance window and potentially no access from approximately 22:00 until completion.
Incoming mail will be queued and will begin to be delivered once the maintenance has concluded.
