Engineers will be performing emergency maintenance on the server web-11 to resolve issues with the email queues on this server between 10pm and 1am tonight.
During this time local delivery of emails may be delayed as engineers upgrade certain components to clear a problem with the system autoresponder module.
No mail will be lost during the maintenance which requires a shutdown of the listeners, application upgrades and then a rebuild of the quota and mailbox indexes.
It is envisaged that this maintenance will take no more than 3 hours to complete.
