Email Bounce-backs

[JasonTh]

One of our customers is getting a bounce-back from some recipients when sending out invoices. The message lists the following error:

Diagnostic-Code: smtp; 554 Your access to this mail system has been rejected due to poor reputation of a domain used in message transfer

Hi @JasonTh 

Thanks for your post. Could you confirm whether you use AccountRight to email out of or Outlook? Usually you would get the rejected error if the receiver has blocked the domain (eg @apps.myob.com) or marked it as spam. Make sure the recipient marks this domain as safe and to mark any emails of that domain as not spam.
