Senders get a second chance to skip the quarantine folder, with our [smtp email service](/email/outbound-smtp).  ##### Firewall for your Inbox --- At times, legitimate mail gets affected. When this happens, the sender is alerted immediately, if their email was blocked. Z ##### Smart and Adaptive Rules --- The system learns and adjusts to messages based on history and the sender’s reputation. All this on auto-pilot and with total [email security](/). ### Traditional Spam Quarantine is Flawed Ask **any experienced IT professional** and they’ll tell you _why the current method of [handling spam quarantine](/spam-filtering/effective-spam-blocking-is-vital-to-your-organization) 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. This is a **tedious and time-consuming process.** ![](https://www.duocircle.com/wp-content/uploads/2018/08/spam_quarantine.jpg)![](https://media.mailhop.org/duocircle/images/2018/08/604250-636359875791182175-16x9.jpg) ### Why Put The Responsibility On Your Users? _One of the reasons_ that this method is less than optimal is because **the responsibility rests on your users** to _clear the quarantine folder._ _This forces_ them to review the spam subject lines anyway – wasting time, energy and resources. This part of the reason that [spam filtering](/email/spam-filtering) folders or quarantines are rarely checked unless people are searching for a “missing message”. > This is **just not an effective approach** to handling quarantined messages. ### DuoCircle Smart Quarantine® Solution Our solution to this problem is a **Self-Service, Smart, Adaptive Quarantine.** At its core, [Smart Quarantine](/spam-filtering/smart-quarantine) 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 mailbox. False negative, a blocked desired (legitimate) email (“ham”) ![](https://media.mailhop.org/duocircle/images/2018/08/SideVector_EmailProtection.png) ![](https://www.duocircle.com/wp-content/uploads/2018/08/easy-to-search.jpg) #### Here’s How it Works **\[1\]** A message is received by our [spam filtering](/spam-filtering) system would have been classified as an 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 CAPTCHA test. **\[3\]** If the sender verifies the message and provides a reason that this should be released 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 do not respond to the challenge email, and almost 100% of false positive senders will click the link to validate their email. #### ![](https://media.mailhop.org/duocircle/images/2018/05/sender-fp-release.png) ##### **Step 2** **Email Sent to Your End User After Sender Validation.** #### ![](https://media.mailhop.org/duocircle/images/2018/05/fp-release-email-enduser.png) ##### **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. ![](https://media.mailhop.org/duocircle/images/2018/05/Report_blocked_email.png) ##### **Admin Quarantine** > _The account administrator can view the domain wide quarantine folder via the message log dashboard in the administrative console._ **Smart Quarantine is included** in our **[Spam Filtering](/email/spam-filtering/)** and **[Email Forwarding services.](/email/email-forwarding/)** It _is part_ of our **[Phishing Protection](/email/phishing-protection/)** with **[Advanced Threat Defense](/advanced-threat-defense/).** ![](https://media.mailhop.org/duocircle/images/2018/05/admin-quarantine-release.png) ## Spam Filtering with Smart Quarantine® --- FEATURES INCLUDED IN ALL PLANS ``` 1 Month - $55.00 3 Months - $148.00 Save 10% 6 Months - $280.00 Save 15% 1 Year - $495.00 Save 25% Get Started ``` ##### Join the thousands of organizations that use DuoCircle --- Find out how affordable it is for your organization today and be pleasantly surprised.
