PowerMTA Management
PowerMTA Management
PMTAcore automates the entire PowerMTA installation and configuration process. Select a server, pick your PMTA version, enter your domain and SMTP credentials, and the app handles everything — OS detection, dependency installation, PMTA setup, firewall rules, DKIM key generation, and service startup.

What It Does
- One-click PowerMTA installation on AlmaLinux 8/9 and Rocky Linux 8/9
- Supports PMTA versions from 4.5r1 to 6.0r3
- Automatic OS detection and dependency installation
- Firewall configuration for mail ports
- DKIM key generation and DNS record output
- SMTP credential configuration during install
- Two installation modes: Single Domain and IP Rotation
- Real-time installation progress with live output
- Saves installation details including DNS records for later reference
Installation Modes
Single Domain — Standard setup using one IP and one domain. Best for low to medium volume sending or when you are just getting started. Simple and straightforward.
IP Rotation — Uses all available IPs on the server, each with its own domain. PMTAcore automatically configures PowerMTA virtual MTAs and a rotation pool so emails are distributed across all IPs in round-robin. Best for high volume sending where you need to spread the load.
