Print | PDF

Barracuda is an email spam filtering tool that blocks potential spam emails sent by external senders.

When an emails is detected as potential spam, you will receive an email from quarantine@ess.barracudanetworks.com that allows you to review the sender, date, and subject of the message. You will also be able to take action on the email:

Select DELIVER to have that message delivered to your primary inbox.
Select ALLOW LIST to have that message delivered to your primary inbox. This option will also add the sender to your Allow List, which prevents future messages from the sender from being quarantined.
Select BLOCK LIST to have that sender blocked from sending you email going forward.
