Here you can select which type of email (incoming/outgoing/internal) should be checked by SpamAssassin. Mails that are larger than the maximum email size in kB are excluded from this. Please note that these settings alone have no effect if you do not use the appropriate rules.
Use Bayes filter
Use the button to turn the Bayes Filter on and off. If you have emails in EML format that were mistakenly recognized as spam (unwanted) or ham (wanted), you can use the two buttons to train the Bayes Filter. Use the "Train Spam" button for spam detected as Ham (false negative) and "Train as No Spam" for Ham detected as spam (false positive).
