Dns Entry question

Hi

I am new to CPanel and today have configured everything and it works.
I got this e mail and do now know what do I have to do.
If you can help me with this.

error;

IMPORTANT: Do not ignore this email.

Your hostname (vmi11837 ) could not be resolved to an IP address.
This means that /etc/hosts is not set up correctly, and/or there is
no dns entry for vmi11837. Please be sure that the contents of
/etc/hosts are configured correctly, and also that there is a
correct 'A' entry for the domain in the zone file.

Some or all of these problems can be caused by /etc/resolv.conf
being setup incorrectly. Please check that file if you believe
everything else is correct.

You may be able to automatically correct this problem by using the
'Add an A entry for your hostname' option under 'Dns Functions' in
your Web Host Manager.

My hosts file:


root@vmi11837 [/home]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost localhost6.localdomain6 localhost6
80.211.218.110 vmi11837 vmi11837 vmi11837.contabo.net


Thanks
