In late (very late) 2009 our SSL certificate provider ipsCA (http://certs.ipsca.org) announced that everyone using their certificates must re-install new versions of these certificate files on their servers for all of their secure sites.
The problem with their decision to re-install all of their certificates is that web browsers haven't had time to react and are falsely displaying errors about bad SSL certificates. ipsCA are currently working with individaul browsers to fix these issues, but have not announced any specific time line.
In the meantime, it is perfectly safe to ignore these errors and continue to login to our webmail as normal.
To assist you, here are examples of the errors you can expect to see in different browsers when accessing school email:
Internet Explorer Firefox Chrome Opera Safari
Internet Explorer skip to top
Click 'Continue to this website'
Firefox skip to top
Click on 'I Understand the Risks'
...Add Exception...
... and then 'Confirm Security Exception - (you should only have to do this once)
Google Chrome skip to top
Click 'Proceed anyway'
Opera skip to top
Click on the 'Approve' button
Safari skip to top
Click on the 'Continue' button
