Unrouteable Mail Domains

[stugster]

I'm getting these error messages relayed back to the nobody account.

The server is able to telnet to domain names such as earthlink.net, so resolving the MX isn't the problem. I also have "Track the origin of messages sent though the mail server by adding the X-Source headers (exim 4.34+ required)" unticked - i.e. switched off.

Any help wuld b appreciated!

Did you send bulk mail ?
