Spam firewall and the way to learn more
Many spammers have been known to try to defeat e mail servers by modifying message headers, which has traditionally been a weak spot in network security. Upon the detection of any such modification on the e mail headers, the Barracuda firewall will then almost always automatically consider these e mails as spam. Barracuda firewall also looks into the content of any received e mail for any of the usual signs of spam. If there are certain spam terms that show up frequently, the Barracuda firewall will weigh the probabilities of such e mail being spam. If the e mail in question is considered spam, the appropriate action according to your user setting will be taken.
