Maintenance will be performed on the IMAP mail server starting from 5 PM this evening continuing through the night. During that time, there will be long periods when staff & students will not be able to read their mail, but mailboxes should be available before morning. Incoming messages received during the maintenance will be queued and delivered to your mailbox once maintenance is completed. It will still be possible to send outgoing messages (provided that your mail client is able to send messages without access to your mailbox).
It has become urgent that this maintenance be completed before the start of the next term, hence the short notice.
