PowerMTA Management

PMTAcore automates the entire PowerMTA installation process. Instead of manually SSHing into your server and running commands, you can install PMTA with a few clicks.

Supported Operating Systems

• AlmaLinux 8
• AlmaLinux 9
• Rocky Linux 8
• Rocky Linux 9

Supported PMTA Versions

PMTAcore supports PowerMTA versions from 4.5r1 to 6.0r3. We regularly update the app to include the latest releases.

How to Install PowerMTA

1. Go to the PowerMTA Installation section from the sidebar.
2. Select the server you want to install on. This can be a server from your Cloud Manager or a custom server you added manually.
3. Choose the PMTA version you want to install.
4. Click Install.

What Happens During Installation

PMTAcore will automatically:

• Connect to your server via SSH
• Detect the operating system and version
• Install all required dependencies
• Download and install the selected PowerMTA version
• Configure firewall rules (opens necessary ports)
• Set up a basic PMTA configuration file
• Start the PowerMTA service

The entire process typically takes 5-15 minutes depending on your server's internet speed.

After Installation

Once installation is complete, PowerMTA will be running on your server. You can verify this by opening an SSH session to the server and running pmta status. You can also manage the PMTA service (start, stop, restart) from within PMTAcore.

Troubleshooting

If installation fails, check the following:

• Make sure the server is running a supported OS (AlmaLinux 8/9 or Rocky Linux 8/9)
• Verify that the server has internet access
• Ensure SSH credentials are correct
• Check that port 22 (SSH) is open on the server
