Schools have been experiencing issues first thing in the morning with the staff email system. Schools normally notice the issue because external emails that they were expecting have not been delivered. This backlog of emails is being cause by the PureMessage filtering system.
To ensure that schools are protected from new threats the PureMessage system updates on an almost nightly basis, allowing it to keep up with any new threats that have been released since the last update.
Unfortunately something is going wrong with this automated process which runs at night. TMC are not the only customers affected and PureMessage are working on a resolution for all of their customers.
ICT are manually doing the updates after a failure to ensure that schools remain protected from even the newest threats. We will keep you updated on the progress of the resolution.
