Quarantine
A quarantine your users can manage, with the rules your IT team sets
Each user signs in to a personal quarantine portal, reviews held mail, releases what is safe and reports what is not. Your IT team decides which reasons users may release.

Release and report selectedMy rulesDelivery history
Built for your users and your IT team.
Release rights by reason
Release rights follow the quarantine reason. Users never release malware.
Scan on every release
Every release triggers a fresh antivirus scan.
Users from your directory
Manual, CSV, Active Directory, LDAP, OpenLDAP, Google Workspace, Microsoft Entra ID, Zimbra or Carbonio; up to 50,000 users per customer.
Quotas and clean-up
A quota per user and automatic clean-up keep the quarantine tidy.
“Always deliver this sender”
When a user releases a message, they can ask to always deliver that sender.
Release with confidence
Users see why a message was held, never its content.
A message opens with its headers, the sender verification and the result of each security layer. The body and attachments are never shown. Before a release the message is scanned for viruses again, and the IT team sees who released what.
- "Release", "Release and report" or "Report to IT administrator", depending on the reason
- "Send PDF to me": the security report goes only to the user's own address
- "Always deliver this sender" works only for senders verified by SPF or DKIM; antivirus and phishing checks still run

Release and report
Users tell the IT team why a message is safe.
When releasing, a user can say why the message is safe, leave a note and ask the IT team to allow the sender from now on, for one address or the whole domain. Up to 20 messages can be released together.

Release rights
Release rights follow the reason a message was held.
The administrator sets, for each quarantine reason, the lowest role that may release a message: mailbox user, IT Admin or administrator. Malware is never released by a mailbox user, and every release, by anyone, is scanned again first.
Quarantine releaseServer settings| Quarantine reason | Mailbox user | IT Admin | Administrator |
|---|---|---|---|
| Spam and bulk mail | May release | May release | May release |
| Sender authentication | May release | May release | May release |
| Blocked file types | May release | May release | May release |
| Risky attachments | May not release | May release | May release |
| Business email compromise | May not release | May release | May release |
| Phishing and malicious links | May not release | May release | May release |
| Malware signatures | Never | May not release | May release |
Default settings; the administrator can change each reason. Every release is scanned again.
Summary email
A summary only when new mail is waiting.
Users receive a short list of newly held messages, every 6 hours by default (1 to 24 hours, chosen by the IT team). The email contains no release links, only a link to sign in, so a fake summary cannot trick anyone. Bodies and attachments are never included.

For your IT team
Every user decision reaches the IT team.
Reports from users wait for a decision: release, delete, block the sender or keep. Messages released by users can be confirmed as safe, which teaches the filter, or marked "Was not safe", which blocks the sender and warns the user.

Storage and retention
Quotas that warn before they fill up.
Each user has a quota (25 MiB by default). At 80% the user and the IT contact are warned; at 90% the user's quarantine is emptied automatically, and both are told. Messages are kept for 1 to 14 days and are deleted, never delivered, when the time runs out.
