Tinned-Mail Requirements

On this page you can find the requirements and limitations of Tinned-Mail. You can also find the configuration of our testsystems.


  • Webserver with PHP support
  • PHP version 4.0 or higher
  • Read permission on configuration files
  • Read and write permission on userdata directory and its files

    • Support PCRE
    • Support Session
    For more information about this, please consult the PHP official website (www.php.net).
