Make a direct edit to one of the core files:
(Remember, this will break during upgrades, so you will need to do it again and again.)
/includes/classes/order.php
Code:
zen_mail($this->customer['firstname'] . ' ' . $this->customer['lastname'], $this->customer['email_address'], EMAIL_TEXT_SUBJECT . EMAIL_ORDER_NUMBER_SUBJECT . $zf_insert_id, $email_order, STORE_NAME, EMAIL_FROM, $html_msg, 'checkout', $this->attachArray);
Replace EMAIL_FROM with '[email protected]'
Then test to be sure your webserver actually allows you to do that, since some don't like you sending from multiple addresses unless you've set up your store to use SMTPAUTH mode for sending emails. You will definitely have a problem if you've left it at the default of using 'PHP' mode for sending email.
