Hi Installed and configured Proxmox Mail Gateway Yesterday and it works fine. Sending and Receiving of internet mails is working fine. Except for today to a certain domain moteco-support.com all the emails is saying accepted/bounced. below is the sample of the transaction. I was forced to revert back to my original configuration to avoid further problem. As we are currently running a test on it and planning to fully implement to our environment. hope someone from proxmox support will reply to my querry.
