EMAIL TAGGING INFORMATION

Email received from senders outside the University will be tagged with notifications in the subject line of the email:

Email TagInformation
[EXTERNAL]

Applied to all email received that originates from outside of The University of North Carolina at Charlotte

The university uses some 3rd party vendors to send emails - these emails may also be tagged as [EXTERNAL]

[SUSPICIOUS]
  • Applied to any email that does not pass security verifications
  • Email marked as [SUSPICIOUS] will be delivered to Inbox
  • Security verifications include:
    • Failed DKIM Authentication (failure to validate)
    • SPF Verification Failures (SPF check failure)
    • Possible Sender Spoofing Detected

Email from valid senders and business partners could be marked as suspicious if not configured to send in a way that meets our security requirements.

If the message is from a trusted University vendor partner (sent on behalf of the University), OneIT Security Services can review - submit a ticket
