Beware of Phishing Email

You may have experience in receiving email that looks like being sent from the "support", "service", " admin", "network/email/web administrator "... etc. of the University, and you were asked to provide your account password by either replying to the email, or clicking a link in the email to access a web page and filling in your password there. Examples of phishing email are enclosed below for your reference.

Please note that our administrators or support staff have NEVER asked and will NEVER ask users to provide password via email . Therefore, these kinds of email in fact were fraudulent or phishing email (also called email scams). They were NOT originated from the University central email system at all, and the sender address (e.g. is usually an INVALID email address.

You are advised to DELETE such email (or email in similar style) immediately when it is received. DON'T reply to the email or click on any link contained in the message. Please refer to the FAQ on "What is phishing email and how to avoid it?" for more details.

If unfortunately you have already responded to this kind of email, please change your password immediately. Password change option is available within the University Portal and in the Email Service home page.
