Introduction

UMIACS has deployed a system with two Barracuda Networks spam firewalls. This allows for enterprise level Virus and Spam scoring and filtering for our email architecture. You can log in to the system either of the two firewalls using your UMIACS email address (username@umiacs.umd.edu) and UMD passphrase:

Mail Flow Through 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. 3:30pm EST from the Barracuda with your quarantine summary. Please note that auto log-in through the link provided in the summary does not work anymore due to security hardening on the Barracudas. Please use the links provided above to log in.

Scoring

The Barracudas will score every message that passes through them and inject varying message headers based on that score. You can then create email filters based on these headers to filter out messages that are tagged as spam by the Barracudas. See BarracudaSpamFirewall/Scoring for more details.

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. Individual mail messages are purged if they are still in the quarantine 22 days after they are first received.
You can search your spam quarantine by following the steps here.

Quarantine Passthrough

If you wish to have the mail that would ordinarily be quarantined by Barracuda delivered to your mailbox instead you can configure this using the Barracuda web configuration.
You can enable this functionality by following the steps here.

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.
