I've set up a website and e-mail account for a client on Go Daddy. The client has started getting failure notices on e-mails he's sent. He's mad and wants me to fix it. I need help understanding the error.
Here's the error:
Hi. This is the qmail-send program at xxxxxxxxxxxxxxxxxxxxxxx.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
CNAME lookup failed temporarily. (#4.4.3)
I'm not going to try again; this message has been in the queue too long.
Here are my questions. What exactly is a CNAME lookup failure? Is it the fault of the mailserver of the person my client is sending TO or is it the fault of the Go Daddy mail server I've set up for my client? If it's Go Daddy's fault, how can I encourage them to fix it?
Lastly, the failure notices are arriving to my client days after he sends the e-mail. If it's going to fail, is there a way to get Go Daddy to deliver a failure message sooner?
Any and all help appreciated!
