In response to the fact that emails sent from University accounts to a range of BT email addresses were being heavily delayed, and having taken advice from BT, IT Services have made changes to our outgoing mail configuration.
This change took place at 10:00 24/8/2016 and email delivery to BT improved during the course of the day. Unfortunately it has had side effects, and so the change is being reverted at 17:00 in line with standard change protocols. An alternative mail configuration will be implemented at 10:00 25/8/2016
Affected email addresses end in @bitinternet.com, @btopenworld.com, and @talk21.com. Messages to these addresses will be queued at Oxford and delivery attempts will continue for 7 days. If unsuccessful after this time your message will be returned to you with a delivery failure message. This affects personal and system-generated messages, including those sent via maillists. Messages sent to multiple recipients will deliver normally for other recipients.
Users may occasionally experience some problems using Oxfile. This is a known problem caused by the load on the system resulting from backups being taken. Usually these interruptions are short-lived and users should just wait for ten minutes before trying again.
We do actively monitor these interruptions to the service and if they appear to be taking an unreasonably long time to clear, we will take appropriate steps to restore the service.
A longer term fix is currently in development and, once that work is complete, these disruptions will cease. In the meantime, we apologise for any problems these brief outages cause.
