Low Scoring Spam
Tells MailScanner what to do with emails determined likely to be spam but that could also be false positives. Options are Deliver, Delete, forward to spam@yourdomain.com and SpamBox. NOTE: If you use the option to forward to a spam address, you will need to create the email account afterward. If you choose the option SpamBox you may have to activate Spam folder on each email account or set up a Mail Client for each user to move Spam to Spam or Junk folder, depending on mail client.
The Low Scoring Spam Setting determines what the initial spam score/threshold will be for Low Scoring spam. The default setting is 5.
High Scoring Spam
Tells MailScanner what to do with emails determined to almost definitely be spam. The High Scoring Spam Setting determines what the initial spam score/threshold will be for High Scoring spam. The default setting is 10.
