I have an issue with Magento 1.9.2.
As you know, 1.9.2 is sending mails only if you put cron.php in cronjob to cpanel.
But as it sends out transactional emails to new customers of a new order, it is adding some previous random customer to CC.
It is very annoying now, and I cannot find any solution, and I'm sure this is some Magento bug.
Do we need to add the following:
core_email_queue_clean_up but where?
We have read the responses and are still not able to understand how to fix it. Any help is appreciated.
