Wow, I am amazed about this 'blame' the customer response! We have just started sending out invoices and they immediately go to junk!?! What Intuit? How is it possible we can set up marketing campaigns and have all authorised mail senders included in our SPF records but Intuit cannot guide or provide a decent solution that will allow their clients to send invoices in the knowledge that they will arrive?

Please advise what DNS config we should use that will allow us to send invoices without them going to junk?

At present I have added "include:e.notification.intuit.com" as this appears to be the sender, however, there is only a hand full of servers behind this so are there others? Perhaps we could have a list of IP addresses so we don't surpass the max to lookup limit?

Thanks
