Customizations not currently supported

  • Alternatives to the Apache web server, such as nginx

  • Mailman cPanel issues

If you are interested in any of the solutions listed above, you should consider a semi-managed VPS or Flex Dedicated Server. These packages are designed for developers and experienced system administrators. They include root access, so you have complete control over your server's customization. You also get access to the exclusive A2 QuickInstaller, which enables you to auto-install software with a single command.
