-====== Some Useful Answers to SPAM Questions ======
-**What are false positives?**\\
-False positives are legitimate e-mail messages that are mistakenly rejected or filtered by a spam filter.
-\\
-**Will I get false positive?**\\
-Yes: for any false positives the sender will receive a bounce message
-indicating the email did not go through.
-Your notification to [[spam@sissa.it]] of the false positive allows us to train the Bayesian filters and
-further reduce the occurrence of false positives.
-\\
-**What is Spam scoring, and the Bayesian Analysis?**\\
-) Spam scoring is the rules based system (about 4000 rules) that looks for characteristics in the email. The Spam scores are used to determine what to do with the email. They do not contribute directly to the future analysis. The rules are updated via the Updates Subscription that we maintain on Barracuda.
-) Bayesian analysis, also contributes to the Spam scoring. This is done using your notifications, so that we can flag some messages as either SPAM, or NOT SPAM in the message log.
-\\
-**How Can I find out if an email that I am missing was blocked by Barracuda?**\\
-You find in the Inbox.SPAM the e-mail stopped by Barracuda because of spam. You receive an e-mail notification concerning e-mail stopped because of virus.
-In case you have more questions you can contact the SIS helpdesk@sissa.it and we will check the message log for you.
