Smart Quarantine®

The traditional spam quarantine system is broken. An end user still needs to check their quarantine folder to make sure that no false positives have been trapped by the system which is a tedious and time-consuming process.

One of the reasons that this method is less than optimal is because the responsibility rests on your users to clear the quarantine folder forcing them to review the spam subject lines anyway, wasting time, energy and resources. This part of the reason that spam folders or quarantines are rarely checked unless people are searching for a “missing message”. It’s just not effective approach to handling quarantined messages.

The DuoCircle Approach is Email Smart Quarantine®

Our solution to this problem is a SELF SERVICE Smart, Adaptive Quarantine, at its core it is a challenge-response system that puts the burden of sorting the Spam message on the sender rather than the recipient. 

  • False positive, a missed spam that slipped through filters into a user’s mail box
  • False negative, a blocked desired (legitimate) email (“ham”)

 How it works

  1. A message is received by our system would have been classified as a FP (False Positive). Rather than discard it or just tag it as spam, we send a challenge (via email) to the sender of the message to validate the message.
  2. The email that the sender receives states that the message looks suspicious and it’s the sender that initiate the release process, after having passed a CAPCHA test.
  3. If the sender verifies the message, and provides a reason that this should be release the recipient is notified via an automated email, with a link to review and optionally release the message.
  4. Since the sender is notified of the blocked email immediately, un-reported spam can be retained during a very short period (for example 1 day).
  5. Once reported however, the retention time is extended (to for example 1 week), giving the recipient plenty of time to check the inbox, find the report, and release the blocked email.

Step 1: Challenge Email Sent to the Sender to Validate their False Positive Message

In our tests 99.99% of spammers to not respond to the challenge email, and almost 100% of false positive senders will click the link to validate their email.

The sender then validates that they are not a robot using the Google reCAPTCHA technology to request the releasing of the message.

Step 2: Email Sent to Your End User After Sender Validation

Step 3: End User Interface to Release the Message

Once the email has been released by the end user it is delivered to their inbox.
