I upgrade from 1.3.2 to 126.96.36.199 a few months ago and have now discovered that customers are not receiving order, invoice, and shipment email confirmations. I have all emails sent through my own server. I tested using a dummy account with a Gmail email address and also a non free email service. The strange part is that customers are receiving the new account and password reset emails. Another odd thing is that I setup BCC for all email confirmations and those are coming through to me fine.
I have noticed since the upgrade that on all the BCC copies of the order confirmations is that in the “To:” field is blank on all emails. When I was on version 1.3.2, the customer’s email address was always in there. Maybe this is the root of the problem?
I would be grateful to any help you could offer.
