Name Server Settings
DNS stands for Domain Name Service. That is the Internet service that allows the world to find your web site when they type in your domain. It translates you domain name into and IP address. The name servers for Computer Tyme are:
ns.reality-dns.com ns.reality-dns.net ns.reality-dns.org
Ordinarilly Computer Tyme will provide DNS services for your domain. If you are new to Computer Tyme you need to go to your registrar and set your name servers with the above information. This gives us control to set the IP addresses of all your hosts and mail exchange records. With three servers in different locations we can ensure that no matter what happens, the world will be able to find where the servers that host your site are.
MX Record Settings
Normally most users don't have to mess with the MX records. But if we are providing front end spam filtering services for you and you are managing your own name server then these are the settings for the MX (Mail eXchange) records:
mx.junkemailfilter.com - Priority 10 mx.junkemailfilter.net - Priority 20 mx.junkemailfilter.org - Priority 30
Ordering and numbering is important. It is also important that you not add any of your existing MX records or and other MX record to the list as it will defeat the way the spam filter works. Here's the instructions if you are Changing your MX records with cPanel.
