E-mail and Anti-Spam - Report Spam

Reporting a False Negative

To report a false negative (mail not being marked as Potential-SPAM when it should have been) you can send that message as an attachment (RFC-822 MIME encoded) to spam@colorado.edu. If you do not know how to send a message as an attachment follow the directions below for your mail client. The message will be passed on to Cisco for evaluation. If deemed spam, Cisco may update the IronPort filters accordingly.

Please note: Senders will not receive a response or acknowledgement of receipt from spam@colorado.edu, nor is there a guarantee that they will never receive a message from that sender again.

Reporting a False Positive

To report a false positive (mail marked Potential-SPAM when it is legitimate), please send the message to falsespam@colorado.edu as an attachment. Note that these messages will be seen by University of Colorado employees as well as by employees of IronPort Systems (a subsidiary of Cisco). By sending these messages, you are acknowledging that they do not contain personal, financial, or otherwise private information.

If you do not know how to send a message as an attachment follow the directions below for your mail client. Please note that the mis-identified message must be attached to the email that you send – we cannot accept “forwarded” messages.
