How important is it to have sockets support enabled in PHP for PHPmailer to function properly?

It is crucial to have sockets support enabled in PHP for PHPmailer to function properly, as PHPmailer relies on sockets for sending emails. Without sockets support, PHPmailer will not be able to establish a connection to the mail server and send emails successfully. 

// Check if sockets support is enabled
if (!function_exists('fsockopen')) {
    die('Sockets support is not enabled in PHP. Please enable sockets support in your PHP configuration.');
}
