SecZim Documentation
Complete documentation for installing, configuring, and operating SecZim — the high-performance email security server for Zimbra and Postfix infrastructure.
Prerequisites
SecZim runs on Linux servers (Rocky Linux, RHEL, CentOS, Ubuntu, Debian). It integrates directly with an existing Zimbra or Postfix installation. Minimum: 2 GB RAM, 10 GB disk, root access for installation.
One-Command Installation
Install SecZim on your mail server with a single command, using your license key:
curl -fsSL https://get.seczim.com/install.sh | sudo bash -s -- YOUR-LICENSE-KEY
The installer downloads the binary, sets up the database, configures Postfix integration, and starts the SecZim service.
After Installation
Once installed, SecZim runs as a systemd service. Verify the service is running with systemctl status seczim. The web dashboard is available on the configured admin port.
Dashboard Access
Access the SecZim admin dashboard through your browser. Default credentials are set during installation. From the dashboard you can manage policies, view live sessions, configure access control, review alerts, and inspect IP reputation data.
Common Commands
Service management uses standard systemd commands: systemctl start|stop|restart seczim. Logs are available via journalctl -u seczim.
Updates & Maintenance
Apply updates with: curl -fsSL https://get.seczim.com/install.sh | sudo bash -s -- --upgrade. The upgrade command applies idempotent database migrations and updates the binary without disrupting existing configuration.
Troubleshooting
For installation issues use the verbose mode: curl -fsSL https://get.seczim.com/install.sh | sudo bash -s -- --verbose YOUR-LICENSE-KEY. For additional support contact support@seczim.com.

Frequently Asked Questions
What operating systems does SecZim support?
SecZim runs on Linux distributions including Rocky Linux, RHEL, CentOS, Ubuntu, and Debian. A minimum of 2 GB RAM, 10 GB disk space, and root access are required for installation.
Does SecZim work with Postfix or only Zimbra?
SecZim integrates natively with both Zimbra Collaboration Suite and Postfix. The same binary supports either mail server through standard Postfix milter and policy interfaces.
How long does it take to install SecZim?
Installation takes about 2 to 5 minutes. SecZim ships a one-command installer that downloads the binary, sets up the database, configures Postfix integration, and starts the service.
How do I upgrade SecZim to a new version?
Run the installer with the --upgrade flag: curl -fsSL https://get.seczim.com/install.sh | sudo bash -s -- --upgrade. Upgrades apply idempotent database migrations and replace the binary without disrupting existing configuration.
Does customer email data leave my server when running SecZim?
No. SecZim is 100% on-premise. All email data, policies, and traffic remain on the customer mail server. Only license activation and update checks communicate with seczim.com.
Where can I get help if installation fails?
Re-run the installer with --verbose to get full output, then contact support@seczim.com with the log. Most installation issues are resolved within one business day.
