In order to assist staff in easily identifying external emails, ICT has implemented a security feature where external emails are clearly identified with “[EXTERNAL E-MAIL]” at the start of the email message.
This disclaimer is a reminder for staff to always use caution when opening emails from unknown email addresses. You should only open attachments from known senders and never provide your username and password.
See below for an example of how this change will look:
