[Plugin: eShop] Order confirmation emails

After making myself crazy with a different e-commerce plugin and all of its sales tax configuration issues, I was very happy to find eShop. It was a little confusing trying to figure out where to start, but now that I have most things sorted out on my test site I am very happy with how everything works. It is almost ready to go live except for one little problem – the confirmation emails are not being sent out.

I did a few test orders as cash sales and I did not receive any email notification of the order (am I supposed to get one?) and the “customer” did not receive an order confirmation email.

I looked at the email template settings and only the default ones were active, so I copied the default info into the cash template and activated that. I then placed another test order with cash payment and still no emails were sent. I placed another order using paypal and no emails were sent then either. I checked that the email address I was using in the eShop settings matched what I was using for paypal so I know that isn’t the issue.

I am using a ymail email address. I tried switching all of my eshop settings and paypal to a different email address that uses my domain name (orders@mydomain.com) and that didn’t work either. I looked through these forums and found this thread:

So I tried using two different smtp plugins and changing the default port but it still didn’t work. I couldn’t even get the smtp plugin test emails to work. I switched everything back to ymail after that and now I don’t know what else to try.

It’s not the end of the world or anything. I can manually send out emails when I get orders because I don’t expect a high volume of sales, but it would be really nice if I could get these automatic emails to work.

I’m on WordPress 2.8.5 if it matters.

Anyone know why I am having this issue and how I can fix it?
