Do you send emails out to large groups of people?
28 Jul 2015
As part of reducing the impact of potentially compromised IT accounts, we put limits on the number of email addresses which can be used from a personal University account.
What does this mean?
There is a limit to the number of recipients per email message, and a limit to the number of recipients which can be used in a 24 hour period.
Shared email accounts are also limited, but they have a higher limit due to the way these accounts are used.
Why are these limits in place?
If a University IT account is compromised due to phishing, a virus infection or other attack, it may be used to send large amounts of junk mail. This has the potential to result in our email systems being ‘blacklisted’ and causing further disruption to University business. These limits reduce the risk of this happening.
How do I know if I will reach the limits?
We don’t publish the current limits, as they may need to change at short notice if circumstances dictate. However, if you do exceed the limit you will get an email in your inbox informing you that your email did not reach the recipients.
How do I avoid reaching the limits?
We always recommend an announcement/moderated list on our ListServ service if you regularly email large groups of people. However, we understand this is not always convenient, so if you are concerned you might reach the limits, contact the IT Support Centre to request an increase.
