Recently, yet more news articles report damage caused by phishing or account hijack. In fact, also here in our university, we receive reports about such damage caused by account abuse. We’d like our users to be very careful about managing accounts.
As an emergency action against incidents such as supposedly abnormal transmission of mail messages, we may temporally lock user’s account without notifying the owner of the account. Under such circumstances, we will interview the user for more information.
We ask for your kind understanding and cooperation.
