No, MailScanner and the MailScanner front-end does not include a spam box feature.
The closest you can get to it with MailScanner is to manually set up
firstname.lastname@example.org mailboxes for each domain in cPanel and configure
MailScanner to forward mail to this mailbox.
However, we do not recommend setting MailScanner up like this
by default for all your users, because if users do not check this
mailbox regularly and delete the spam from it, spam will start getting
bounced. This will bounce back spam to innocent parties, clutter the
exim queue, risk your server getting reported for spamming, and increase
the overall load on your server.
