At times, most departments may have genuine needs of sending email to a large number of external recipients, and yet quite a number of such email was either bounced as undelivered email or returned with undeliverable notifications by the recipients' email servers due to the following reasons:
Sometimes the number of such bounced email or undeliverable email notifications was so huge (as the email is often delivered at the same time) that it jammed our email servers, causing prolonged sluggish email delivery. Worse still, complaints were received to ask the CityU to stop sending the email for reasons such as the recipients considered it as spam mail, or the email attachment caused the recipients' email disk quota severely depleted, resulting in their subsequent incoming email being missed. As such, departments have to exercise care when sending email to a great number of external recipients. Moreover, it can also devastatingly damage the image and the operation of the University if this kind of email is sent without prior consent of the recipients. For example, if some recipients do make complaints to those Real Time Spam Black Lists (RBL) sites and have the university email server being successfully blacklisted, no CityU users will be able to send email to all those organizations that are using the RBL as a means to fight spam mail. Besides, it is also undesirable to send unsolicited email with an attachment as the recipients may not know who you are and whether your attachment is safe to open. If however you do have to send an unsolicited email with an attachment, please limit the size of the attachment to a minimum as the acceptable size limit of an email message for many email systems is well below 5MB.
Please watch out for the following upcoming laws related to the spam email and make timely changes to the respective business operations:
