BarracudaSpamFirewall
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 approximately 3:30pm US Eastern from the Barracuda with your quarantine summary. Please note that the links provides in the Actions column in the summary do 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.
Allow Lists, Block Lists, and Bayesian Filtering
- You may also setup allow lists, block lists, and Bayesian filtering options through the Preferences tab at the top of the Barracuda web portal.
