Each user has a quarantine box which holds messages DSPAM thought was spam. Rather than simply delete these messages, the quarantine box gives the user the ability to identify the occasional false positive and re-learn them as innocent emails. This is a very important step in the learning process that many other tools don't provide. It is understood that no spam filter will be 100% accurate, and therefore it is important to be able to learn from its mistakes. DSPAM's quarantine makes it much easier to manage spam than some other solutions because it sorts the quarantine based on confidence. Therefore, any likely false positives are going to rise to the top of the quarantine for easy review.

Users who would prefer to tag spam may specify this in their preferences. Systems administrators looking to integrate DSPAM with fancy IMAP folders can also find support for this.
