DNS temporary failure

[sandipcd]

I am sending email from our email id vendor@hostingultraso.com to surojit@mindandmatter.in. But the outgoing email is bouncing back to us and error says "451 4.4.0 DNS temporary failure (chkuser)"

How can I solve this problem? We are using Kloxo-MR.

Something wrong with dns detect from qmail. Inform here 'cat /etc/resolv.conf'.

I have changed it. How do I check now it is working or not?
