Hi,
I am using Astaro's Mail Security Gateway, behind it is a CentOS email server. Recently i find that bounce back messages were not sent back to the original senders. I can see in Astaro > mail Security > Mail Manager > SMTP Log, emails were logged and bounced. But regardless of which email provider I tried, I still don't get any bounce back messages.
I am wondering if there is a setting in Astaro that I need to configure, so that it will allow the bounce-back messages to return back to sender. Any help is greatly appreciated. Thanks so much.
