I have ce 184.108.40.206 installed and it appears that all of the emails are sending except for the Order notification email to the set "Sales Representative" email set up in System>Configuration>Store Email Addresses.
I'm running Linux CPanel virtual hosting (customer's choice) through Godaddy, I have a cron job set up to run every minute pointed at cron.php, their company email is through google business apps and I have the MX records set up correctly for that.
It sends the order invoice to the customer email address, the contact form works, and if I put an email address in the "Send order copy email to:" field in System>Configuration>Sales Emails and set it as "Send Order Email Copy Method" to "Separate Email" it will send the order notification to that email address.
So to summarize: When and order is placed on front end, the customer receives an email and whatever email address is put into the Send Order Email Copy receives an email, but no matter what email address is put in as the Sales Representative email (whether in domain or different domain) it does not send an email to Sales Representative.
What am I missing?
