Scrollout F1 is a free, open-source email security gateway that acts as an inbound and outbound proxy to protect mail servers (like Microsoft Exchange, Postfix, or Zimbra) from spam, viruses, and data leaks. It processes and filters messages before they reach your primary server. Hardware & OS Requirements
OS: A clean, minimal installation of Debian Linux (Debian 9 or 10 is ideal; newer versions may require modified fork repositories). RAM: Minimum 1 GB. Storage: Minimum 30 GB. Network: One static IPv4 address. Step 1: Open Essential Firewall Ports
Ensure your network firewall allows the following traffic to and from your Scrollout F1 server:
Inbound: TCP port 25 (SMTP mail traffic), TCP port ⁄443 (Web management GUI).
Outbound: TCP port 25 (Mail delivery), UDP port 53 (DNS and RBL checks). Step 2: Install Scrollout F1 via CLI
Log in to your clean Debian server terminal as the root user and execute these commands to download and run the installer:
apt-get update && apt-get install sudo -y sudo -i cd /tmp wget http://sourceforge.net/projects/scrollout/files/update/scrolloutf1.tar/download -O scrolloutf1.tar tar -xvf scrolloutf1.tar chmod 755 /tmp/scrolloutf1/www/bin//tmp/scrolloutf1/www/bin/install.sh Use code with caution. Step 3: Initial Web GUI Configuration Open a browser and log in via https://YOUR-SERVER-IP/. Change the password immediately when prompted.
Navigate to Connect: Enter your server’s hostname, static IP, subnet mask, gateway, and DNS servers. Step 4: Route Inbound Traffic Navigate to Traffic in the Web GUI. Enter your Domain Name (e.g., yourcompany.com).
Enter the Inbound Destination IP (the actual IP address or hostname of your internal Exchange/Postfix mail server).
Click Apply to save. Scrollout F1 will now know where to send clean emails. Step 5: Update Public DNS Records
To put the gateway into active production, update your public DNS records through your registrar: SourceForge Scrollout F1 download | SourceForge.net
