External Email Tags
Phishing attacks are a top cybersecurity threat to Duquesne University. These types of attacks involve the use of malicious attachments or links in an email to steal personally identifiable information (PII). To continue to combat phishing, Computing and Technology Services (CTS) will implement external email tags on August 6.
How Do External Email Tags Work?
External email tags will notify you when an email has been sent from someone outside of Duquesne University. The goal of external email tags is to alert you to potential risks of clicking on links or opening attachments in emails sent from an unrecognized sender.
When you receive an email from a email@example.com address, such as Gmail or Yahoo, the text [External] will be added to the beginning of the subject line. External email tags will appear when viewing your Duquesne University email in the Outlook Web App (OWA), email clients and mobile devices.
When composing an email to a firstname.lastname@example.org address, you will see an alert indicating that the recipient is outside of Duquesne University.
Example of External Email Alert
This alert will only appear when accessing your email with the following applications:
- Outlook Web App (OWA)
- Microsoft Outlook 2010 or above (Windows only)
- Outlook App for iOS/Android
Is an email unsafe to open if it contains an external email tag?
An external email tag does not indicate that an email is unsafe. However, you should be cautious of clicking on links or opening attachments if you do not recognize the sender.
If I forward a copy of a tagged email, will the external email tags also be forwarded?
Yes, the text [External] added to the beginning of the subject line will be included in any forwards or replies to the message.
What does it mean if I receive an external email and it does not have an external email tag?
External email tags are applied to the majority of external emails sent to email addresses ending in @duq.edu. However, it is possible for an external email to be delivered without an external email tag. In these cases, CTS recommends proceeding with caution when viewing the message.
Will external email tags interfere with my ability to receive external emails?
External email tags will not interfere with your ability to receive emails sent from an external email address.
