    New Lightening Speed Email Server

    For the past few months, CityU had been bombarded with an increased number of spam email. Out of the hundreds of thousands of emails our servers process each day, sometimes over 90% are spam. (In Asia Pacific, roughly 91.8% of all emails are spam.) Only a few percent of our incoming email are actually useful. This has caused our email servers to be quite overworked in filtering out what is real email and what is spam. In the worst case, you may have noticed a several hour delay before your email gets to its final destination. As of early this week, thanks to our Computer Services Centre (CSC), we have installed a brand new high-powered email server, running a collection of newer state-of-the-art anti-spam technologies, that include IP blocking, IP reputation, advanced keyword analysis, etc. The result is a greatly noticeable improvement in processing speed. Your email should now get to its destination within seconds!

    By the way, I would like to take this opportunity to remind everyone that there is an additional “Junk Mail Filter” option that you can select if you would like a “stronger” spam filter. You can set your filter option by clicking “Account Management” and then “Setup Junk Mail Filter” in our email portal.
