Solved my own problem, here is what I did just in case other magento users have same problem as me.
under “order” you should see “Send Orders Email Copy To” a blank box, I type my store’s general sales email account on it, and then on the second line “Send Order Email Copy Method” I selected “Separate Email” so that customer doesn’t get confuse on emails with Bbc.
I was presented with another solution but I never tested out because the above solution worked.
This other solution (unverified) is to install this magento app: http://www.magentocommerce.com/magento-connect/ASchroder/extension/1865/aschroder.com-smtp-pro#BVRRWidgetID
App. says its only compatible with 1.5 but people have commented that it is compatible with 1.7.02 but I’m not going to test it out since I can finally receive email for new orders now.
