Customer is not receiving order confirmation email

I have just been notified that our customers are not receiving order confirmation email. They used to work fine. I just tested an order and the store received one but me as the customer did not. I have checked the other support postings about this but I think all my settings are ok.

I have everything enable except: Order creation notification, Order cancel & Subscription expired.

I did try the email modification. I took one of my test orders and changed it from confirmed to cancelled and I did get a copy of it in the email. Then I tried another test email (using local pickup and paypal or send check) and I received the store email but not the customer email. I even when back a month or so to see my emails from previous test orders (had both store and customer)

One odd thing - about a week ago I sent out an email newsletter with ACY Mailing - I have a list of about 2400 and usually get about 8 to 40 bounces - This time I had 163 bounces. Could ACY mailing be tied in with this?

I set another test order to "refund", set notify customer to yes & new fields come up and then clicked ok. I did get this email ok. Then I sent in another test order and did not get a "customers email".

Just so I am not getting things confused - this is what I received from the test: "Customer Order: 5210 - Schnute" (only 1 email)

2 or 3 weeks ago I would get 2 emails:
"Your order No. 5143 is now Confirmed at www.honeyflowfarm.com/ " and
"Customer Order: 5143 - Schnute" (This last one is the only one I receive now)

I was trying to show that a few weeks ago I was getting the correct emails:
"Your order No. 5143 is now Confirmed at www.honeyflowfarm.com/ " (the one that I am missing now) and
"Customer Order: 5143 - Schnute" (Schnute is my last name and the test customers name - substitute "Customer Order: 5143 - nicolas" is you submitted the test order)

Now all I get from the test order is: "Customer Order: 5210 - Schnute(nicolas)" and I do not get the customer confirmation order. Shouldn't I be getting the customer confimation on the test order?

I think I did edit something in the past with the help of you guys but I will starting over describing the problem.

I just created a new test order on my site from "Nick nicolas" and sent it in as priority mail & pay pal (although I did not finish the pay pal part) - I used my wifes gmail address (and I just tested it ok) - the order went through and we received the normal email from our store: "Customer Order: 5214 - nicolas". WE DID NOT GET AN ORDER CONFIRMATION AT MY WIFES EMAIL!

Then I went into hikashop orders and "cancelled" the order, the screen came up and I selected "yes" to notify customer and I checked that mywifesgmail address was ok - and I DID NOT get a copy of the cancellation from the store (I dont know if I was supposed to) BUT I DID GET THE CUSTOMERS CANCELLATION IN MY WIFES GMAIL ACCOUNT. ("Your order No. 5214 is now cancelled at www.honeyflowfarm.com/ ")

I never did get the original customer confirmation at my wifes gmail. This is the problem.

OK - Here is an email from an order recently:

"Subject: Re: Customer Order: 5213 - Hodges (I sent this personally)
Thank you for the order. We will ship it to you shortly. Could you do me a favor and email me back if this is the first order confirmation email you have received or did you get one within a few minutes of placing the order?"
She responded:"No I never received a confirmation. I used my discover card and....Thank you! Amy Y. Hodges"

Then I sent in another test order to Nick nicolas - I sent it priority mail and credit card (authorizenet)- order went through ok and I received this email from the store: "Customer Order: 5217 - nicolas" AND NOTHING IN MY WIFES GMAIL ACCOUNT. Then I went into hikashop and changed this order to cancelled with notified customer - yes --- And then I do get the email: "Your order No. 5217 is now cancelled at honeyflowfarm.com/ " in my wifes email.

OK - Thanks - It is working now. There was a reason I unchecked it - but I do not remember. Something to do with getting duplicate emails (& info from one of my posts - or someone else's, but I may have changed my setup since then.
