Hotmail wont deliver emails to our school as of today!?
A user has just pointed out to me that her daughter couldnt email her. After a little bit of investigating it seems if you try and email someone in the school from a hotmail address you recieve the following bounce back email;
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
<my email address>
It attaches a random file which i have no idea what it is, if i open it with notepad its just gobbledegook so theres nothing really that is very useful to determine why they aren't being delivered.
The user says her daughters email her from hotmail addresses regualrly and have always worked until today.
Any ideas on where to start at getting to the bottom of it?
