Since the beginning of June, any invoice that we email (as a link, not as a PDF) to any customer with a Bigpond.com or Bigpond.net.au is not getting to them.
The email does not go into their trash, spam or junk - they simply do not receive it. They also do not receive the reminders. These are all private customers so I dont have any IT department to go to at their end. There are no error reports at either end.
I believe that Bigpond may have blacklisted mailto:Invoices@apps.myob.com.
Is there a way to change the displayed senders address, or a way to whitelist us to bigpond?
I have not had any solution provided as yet by the support line. Please help.
