Change order email from my store to from customers email?

[MagicMan]

This is what you need to do:

/includes/classes/order.php
around line 1012 towards the bottom you will see:

$extra_info['TEXT'], STORE_NAME, EMAIL_FROM, $html_msg, 'checkout_extra', $this->attachArray);

This line needs to be changed to:
$extra_info['TEXT'], $this->customer['firstname'] . ' ' . $this->customer['lastname'], $this->customer['email_address'], $html_msg, 'checkout_extra', $this->attachArray);

This will receive your order email to come from cutomer name and email in the subject so that it will automatically attach to your contact in any contact manager software like Act or Goldmine.

Hope this helps. Thanks for the fast relpy.
