Email, Spam Control, False positives or negatives

I signed up for Spam Control but I'm still receiving spam. OR A legitimate email was caught by Spam Control.

Technology Services can review and adjust some filtering rules and thresholds.  Samples may be submitted to the vendor so they may update the automated filtering.  We may be able to offer suggestions to our customers to reduce future occurrences of unscreened spam or quarantined legitimate email.

Unscreened Spam

Spam is dynamic and each campaign changes tactics to try to get past current filters.   However, Spam Control does not block or filter messages from legitimate advertising message and you should click the unsubscribe button to be removed from that advertiser's mailing list. If you aren't sure how to unsubscribe from such mailing lists (or if you aren't sure if the company is reputable and will actually remove you from the list), then simply add its email address to your Blocked Senders List (see solution Email, Spam Control, How to create a blocked senders list ).

If you still receive spam in your mailbox, then:
  • Send the suspect message to:  report-spam@illinois.edu.  This email address automatically submits the message to our vendor for spam evaluation and rule upgrade.
  • You can check the message to verify it passed through Spam Control. You can determine if the message passed through Spam Control by checking the message's full headers (see solution Email, Exchange, How do I view mail headers? ). If the message does not have X-Spam-Score, X-Spam-Details, and X-Spam-Origsender tags, then the message did not get processed by Spam Control.
  • Verify the sender is NOT on your Safe list.  See the Managing Safe and Block Lists KB article.
  • Add persistent senders or domains to your Blocked Senders List. 

Quarantined Legitimate Email

If you have a legitimate email message misidentified as spam, then:
