Earlier today I received this from QB support:
Good news, the investigation After sending invoice customer receives message: Error: Invoice undelivered has been resolved for QuickBooks Online. If you are still experiencing this unexpected behavior, we would ask you to reach out to your online support team for further assistance.
And then recieved a call and email from the contact in support that has be managing my open case. He was looking for feedback on the functionality.
At this point I can see the invoice emailing is returning to functional. Without certain details I can’t close this out though.
167.89.58.229 is no longer listed in SpamCop and was successfully used in an invoice test this afternoon.
167.89.58.138 is listed in SpamCop.net though it will be off that list in 17 hours if no other spam is sent from that address.
167.89.82.160 is listed in SpamCop.net though it will be off that list in 18 hours if no other spam is sent from that address.
I would expect invoices sent from either of the last two IP addresses to fail in some cases until they delist tomorrow. Hopefully QuickBooks has those two offline until delisted.
Some of the addresses are listed in rarely used spam lists such as JustSpam and S5h, but those are so unused that they are not an issue and I would expect them tp fall off soon. The listing in SORBS that I noted last week has already delisted. QB should be watching this, all the time, and there are services that will monitor it for them.
This is going to need monitoring for a while as we don’t know how the fix was done. Hopefully this is a solid long term fix and not a Band-Aid.
The sad part here is what it took to get this fixed, this should have been done months ago. What a total waste of so much time by so many people simple because QB could not do their job.
Frankly I want to see some coin back, I think it is deserved.
I will check back in around noon tomorrow.
