Hi,
We used core/default order email sending functionality using cron job. When user place an order the email goes to the same customer who place order as well as other previous customer too.
We checked the database core_email_queue as well as core_email_queue_recipient table which shows the correct functionality of entries. Means the recipient id and message id of previous customer as well as currently ordered customer are different so its not an issue to same message id send to two different customer.
Still we stuck the issue regarding order email sending, so how to resolve this issue.Please possible to reply soon.
Regards,
Ashwini.
