Hi Guvna2323,
The error message suggests that the issue is on the recipient's side of emailing. I recommend having your recipient check if any MYOB email origins are blocked by their email service. They can check their spam or junk folders, email rules, and the Mimecast Personal Portal to see if the sender's email is blocked. If they find that MYOB emails are being blocked, they should whitelist the MYOB email addresses or domains.
