Invoice not sending to a particular customer

[LisaS1]

I have one customer whose invoices will not go through to their email account as of three days ago.

I can email this address from my email account, but it won't accept it from MYOB.

Is there a way to fix this?

Hi @LisaS1 

The email may be rejected by your customer's end, please do have your customer to whitelist/allow emails from noreply@apps.myob.com to come through. With this done, if the problem persists, please look for the “Undeliverable” notification email sent to you, it would contain a diagnostic code within, please provide the exact code which would tell us more about the problem.
