Everyday I get an email with this "Unable to resolve your hostname (HOSTNAMEHERE) to an ip address. This means that there is no dns entry for HOSTNAMEHERE. Please add an 'A' entry in your dns. Some are all of these problems can be caused by /etc/resolv.conf being setup incorrectly. Please check this 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 ' under ' Dns Functions ' in your Web Host Manager" ==== Will this error have any effect on my server if I don't get it fixed?
Yes, it will, as the server will use the hostname for many different things. Have you checked the files it listed to ensure things are correct?
In reality, not really! But to fix this, then you may follow this article http://kbsupport.net/support.php?do=viewquestion&faqid=8
To fix this problem, you just need to set an A record for your server Hostname. You can automatically add A record from WHM -> DNS Functions -> Add an A entry for your hostname Kailash
