Hi Paul, 

We'd be more than happy with the emails being sent by quickbooks<@>notification.intuit.com but Quickbooks themselves have confirmed that the emails are set to be "sent" from our email address via spoofing. I've spoken to many many advisors at this stage who have all confirmed the same thing so not sure if this is due to it being a new subscription (there are several differences already compared to older subscriptions which still have certain features enabled) or whether it's because it's an advanced subscription - I have absolutely no idea.

In the US they are able to set Smtp settings to actually send from your own domain but here it isn't even passing through the exchange as its trying to spoof but is being blocked due to DKIM being enabled. Honestly why we have no option to just send fromquickbooks<@>notification.intuit.com is beyond me as this would solve our issues!

In response to your advice about customers whitelisting the email address, it's never hitting their mail servers in the first place. 

An absolute disaster of a service! They keep confirming that it is "working correctly as designed"
