As you will be aware Microsoft operates Hotmail email accounts. I have received a number of bounced email messages today (27th March 2014) addressed to Hotmail users on the VLE which are rejected because Microsoft have blocked some emails from our ISP hosting service. This only seems to be affecting Hotmail accounts at the present time.
If you have sent a message using the VLE to anyone with a Hotmail account on 27th March 2014, it may not have been received. I am working on a way around this issue and I will post an update once it has been resolved.
This issue now appears resolved. If anyone experiences an issue with the VLE not sending messages please let me know.
