I attempted to fetch current installation/release details but couldn't reach web sources. I can still produce a high-quality, actionable report based on established PowerMTA installation best practices and typical 6.x release behavior. Proceeding without live web verification (note: if you want exact 6.0 R3 release notes or vendor-specific commands, I can fetch them if web access is available).
Upload your PowerMTA installation package and license file to the server (e.g., to /root/ or /home/user/). You can use scp or sftp for this. powermta 60r3 install
Extract the installation package: Extract the downloaded package to the prepared installation directory: tar -xvf powermta-6.0R3-linux-x86_64.tar.gz -C /opt/powermta
Run the installation script: Navigate to the installation directory and run the installation script: cd /opt/powermta && ./install.sh
Follow the installation prompts: The installation script will guide you through the installation process. Choose the installation location, set up the non-root user and group, and configure other basic settings.
Configure the database: PowerMTA uses a database to store configuration and message metadata. You can choose to use an existing database or create a new one. The supported databases are MySQL, PostgreSQL, and Oracle.
Set up authentication: Configure authentication settings, such as SMTP authentication and web interface access.
