Since update I am receiving messages about emails being undelivered. It is happening with invoices, statements and overdue invoices that I set up ages ago to send to clients as a reminder. Seeing if there is anyone else experiencing this
we are also having the issue of invoices / quotes not sending - did you find a solution???
No. It obviously must be an issue MYOB needs to fix since the update. Happening to too many
We are also getting the same. Spamhaus seems to be blocking MYOB/Mandrill. Most of the time the Undeliverable message contains the below at the bottom but when I click on the link the resulting page at Spamhaus says the IP address is fine.
