Introduction

UMIACS has deployed a system with 3 Barracuda Networks spam firewalls. This allows for enterprise level Virus and Spam scoring and filtering for our email architecture.

Mail Flow Through Barracudas

  • Currently users that receive mail at Exchange or our new IMAP service will be serviced by the Barracudas.
  • The first time your mail flows through one of the Barracudas it will send you a mail with a new username and password. Subsequently you will receive every day (unless you configure otherwise) a mail at approx. 3:30 EST from the Barracuda with your quarantine summary.

Quarantine

  • Mail that has been deemed as spam will be kept on the Barracudas in quarantine. It will not be delivered to your mailbox unless you configure the Barracudas to do so.
  • Your quarantine will be preserved for 21 days. If mail is held for longer, then it will be purged. At the bottom of your 3:30 quarantine mail you will see a link that will take you straight to your quarantine.

Whitelists, Blacklists & Bayesian Filtering

  • You may also setup whitelists, blacklists, and Bayesian filtering options through the Preferences tab at the top of the Barracuda web portal.

More Information

  • For more information on how to use the Barracuda please download the user's guide:
