Since config/config.php is a PHP file, SquirrelMail can also be configured manually with the editor of

your choice. A sample configuration is provided in config/config_default.php, so copy

config/config_default.php to config/config.php and then edit config/config.php to match your

installation. The configuration options are documented within the file to help you make the right

choices. Note that manually configuring SquirrelMail needs you to follow the PHP syntax. Make sure

that there is no trailing end of line character and save the configuration.
