Using EasyDNS to manage external DNS for e-smith

      The easiest way to manage your external DNS for the e-smith server is to use EasyDNS's DNS-Only package. I'll describe how I have my domain setup as an illustration

      First of all, because I need a site that is always up, I have some virtual hosting space where I run all my mail and my main website (this site).

      To accomplish this, I set up EasyDNS as follows.
         1. Enable dynamic DNS support. You'll need to select the "e" at the top of your domain settings and set the "Dynamic DNS option enabled for my domains" option to "on". Once you've done that, each domain will show a line that looks like "Dynamic DNS is:" and then a link labeled "enabled" or "disabled". Make sure the domain you want to be dynamic has this set to enabled.
         2. Your top-level host (i.e. domain.com) needs to be set to the IP address of your main web host (wherever you want "www" to point). Then set up an alias www.domain.com that points to domain.com. Other common aliases would be something like ftp.domain.com.
         3. Your mailhost also needs to have its IP set, even if it's the same as your domain. After saving this change, you'll also need to edit your MX settings to include mail.domain.com as the handler for domain.com.
         4. Pick a subdomain for your e-smith server. This is what you will also have to set your domain name in the server config to. I make this the same as my workgroup name, so your the subdomain would look like "workgroup.domain.com". Add this host to your EasyDNS settings.
         5. Add any other subdomains as aliases. I have a bunch of other subdomains (e.g. testing.domain.com, gallery.domain.com, etc. etc.) with corresponding virtual domains set up in e-smith. In the EasyDNS interface, create all of these as aliases that point to your main subdomain (i.e. workgroup.domain.com from the previous step).
