Retrain Messages Sometimes it happens that messages are classified incorrectly by the filtering system. A  false positive  refers to a message that was incorrectly classified as being Spam. A  false negative  refers to a message that was incorrectly classified as NOT being Spam. In other words,  false positive  messages end up in the Spam folder instead of the Inbox, while  false negative  messages end up in the Inbox instead of the Spam folder. We have several methods to help retrain our system so that it doesn't make the same mistake again: In your configured IMAP account or in Webmail, simply drag the message from the Inbox to the Spam folder or vice-versa and keep it there at least overnight Retrain using the  Spam Quarantine  feature of the User Control Panel: Go to Unknown macro: {link-window} https://cp.emailarray.com Log in using your full e-mail address ( user@domain.com ) and current password. Click on the  Spam Quarantine  icon Search for the Spam message by selecting the appropriate date, optionally defining a search term and clicking on the  Display  button Mark the checkbox next to desired email and click on one following buttons:  deliver and whitelist  the sender,  deliver only  or  delete Forward the offending message to the specific retraining address as defined by your Administrator. Usually they are of the form: spam@domain.com & notspam@domain.com
