BarracudaSpamFirewall

Introduction

UMIACS has deployed a system with 2 Barracuda Networks Spam Firewalls. This allows for enterprise level Virus and Spam scoring and filtering for our new email architecture.

Mail Flow Through Barracudas

• Currently users that recieve mail at Exchange or our new IMAP service will be serviced by the barracuda's.

• 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 recieve every day (unless you configure otherwise) a mail at approx. 3:30 EST from the barracuda with your quarantine summary.

Quarantine

• Your quarantine will be good for 21 days, if mail sits for longer than that in your quarantine it will be purged so please check your quarantine. At the bottom of your 3:30 quarantine mail you will see a link that will take you straight to your quarantine.
  • If you receive a security warning message after clicking this link, you need to add the UMIACS CA (certificate authority).

Whitelists, Blacklists & Bayesian Filtering

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

Previous Spam/Virus Filtering

Barracuda Spam Filtering

• NOTE: This will be replacing the current spamassassin solutions we have deployed and as we migrate all old users off of reptoid spamassassin will no longer be available to use in line with our mail environments.
