Hi
I'm using MYOB essentials and am having the same issue when I email an invoice to an overseas client. Everytime I've sent it it bounces back. I have not had any issues with emailing invoices to Australian clients. I've checked and rechecked the email address which is correct. The only way I can email it is to cc the invoice to my email addres and forward from there and it is successful doing it this way. Can anyone help with this issue?
