Quarantined vs. Blocked Messages
Our email gateway continuously scans incoming traffic to balance cybersecurity with legitimate business deliverability. Held messages fall into two strict classifications:
Quarantined (Actionable): Borderline emails scoring between 3.5 and 5.9 (such as bulk vendor digests, newsletter updates, or partner emails with minor formatting flags). These are held safely and can be delivered by you.
Blocked (Non-Recoverable): Severe threats scoring 6.0 and higher, including malware payloads and sender domain forgeries. If a legitimate business email is "Blocked", this will require the IT department to manually allow this message to be sent.
Viewing Quarantined/Blocked Messages
1. Navigate to https://ess.barracudanetworks.com/ (or "Email Quarantine Portal" managed bookmark).
2. Sign in with Microsoft credentials (same password that is used for PowerBI/Candidate Reports)
3. Once signed in, all recent email activity will be presented. If you are looking for a specific email, you can filter via a specific timeline or action taken:
Manually Sending Quarantined Messages
1. Once a message is found (that needs to be sent manually), you can follow the screenshots below to bypass the initial quarantine by the security gateway:
Creating Custom Sender Policies/Whitelists
Users can also create custom sender policies, that can allow/block any future mail (if a legitimate email was blocked or vice versa)
1. Navigate to the "Settings" tab, and select "Sender Policy"
2. Enter a specific email address/domain, select block/exempt, and then finally select "Add":
These additional user permissions help aid the network in preventing false positives from hindering legitimate business activity. Again, please note that the IT department can only manually send any "Blocked" mail -- as normal business correspondence should NOT fall within this category.
If there are ANY questions or concerns regarding these topics, please submit an IT helpdesk ticket, and we can discuss this further!
