I have the most recent version of ZenCart and the Google Checkout module set up on my site having a problem with the zencart confirmation emails.

1. Google Checkout is my only payment option.
2. I am able to process transactions in sandbox.
3. Transactions are appearing in both Google Checkout and the Zen Cart Admin. Inventory is subtracting correctly.
4. A new customer account is being created based on the information entered into Google checkout.
5. Google Checkout is sending confirmation emails to both the customer and the admin.

However, zen cart is:
1. Not sending an email to the customer email address
2. Not sending a confirmation email to the admin.
3. Not send an email confirming the account creation.

I tried another test:

I enabled Check/Money order checkout and processed and order through it. Zen-Cart successfully sent email to the customer and to the Admin

So I think the email configuration is set up properly.

I have browsed thru entire forum for an answer...but no luck.

Appreciate if experts can guide me through a resolution.
