Enable or Disable the Bayes Database system server-wide.

Enable or disable Bayes auto learning. If enabled, the system will automatically train the Bayes database by analyzing messages that have a score that strongly suggests that they are spam or non-spam.

Enable or disable IMAP training. With Bayes IMAP training enabled, there will be two folders created for all e-mail accounts on the system: “Learn Spam” and “Learn Ham”. You can then put SPAM emails in the “Learn Spam” folder and non-spam in the “Learn Ham” folder. This will train the Bayes system on which emails are Spam and which are Ham (not Spam). The training occurs once daily, after which the folders’ contents are purged.

The maximum number of e-mails that will be trained from each of the IMAP Training Folders, “Learn Spam” and “Learn Ham,” each day.

enable or disable the Bayes global database. If enabled, all the Bayes data will be stored as a single global user. If disabled, each e-mail box user will have their own Bayes database to store bayesian data. “Disabled” is considered more effective for fighting Spam, but requires all e-mail users to train their messages individually, and uses more disk space, compared to the global database option.
