Using CRON with Postman

Great plugin, I’m wondering if there can be an improvement over performance of it though.

I have experienced when sending out emails, especially when sending more than one, that the server becomes very unresponsive.

I have modified the definition of wp_mail and have tested a few times and works ok. I’m wondering if you can review making following changes. I am just copying something I have found on Internet, so I do not know if the code is faultless.

In wp_mail, replace with following code.

$args = func_get_args();
$args[] = mt_rand();
wp_schedule_single_event( time() + 5, 'cron_send_mail', $args );
return true,

——————————————————————-
Then add action and functions to handle the scheduled task

add_action( 'cron_send_mail', 'cron_send_mail', 10, 10 );

function cron_send_mail() {
    $args = func_get_args();
    // Remove the random number that was added to the arguments
    array_pop( $args );
    call_user_func_array( 'postmanmail_cron', $args );
}

function postmanmail_cron(){
	$args = func_get_args();
// create an instance of PostmanWpMail to send the message
	$postmanWpMail = new PostmanWpMail ();
	// send the mail
	$result = $postmanWpMail->send ($args[0], $args[1], $args[2], $args[3], $args[4] );//$to, $subject, $message, $headers, $attachments );
	// return the result
	return $result;
}
