What is a Sub-Domain?
A sub domain is one which resides under your top-level domain
name, but in many ways behaves as a "totally independent domain". You'll
observe that many of the larger corporations use these, as they're somewhat
more professional looking, and do a better job of creating an independent
presence for service or product lines, which appear as separate web
entities. This support site is an example of a subdomain (support.theservercenter.net).
Thanks to the control panel, this task has been made easier
than ever and can be achieved as follows:
Yes, you'll observe duplicates of all "configured pop email accounts" appearing beside the sub-domain, and or all sub-domains you've created. Now I know you'll be tempted to use (what appears to be) a perfectly good email addresses, BUT please "Don't!" This is a feature that is in final development. While it may look somewhat confusing at first glance, it's really not. In the near future, you'll be able to configure these email accounts for use with your sub-domains. For example, if you configured support.yourdomain.com, then you'll be able to use the address firstname.lastname@example.org.
For the time being, please configure email addresses that correspond to your standard "top-level" domain, and just ignore the sub-domain duplicates. ALSO: Any duplicate sub-domain email address's you see appearing in your pop mail setup configuration "DO NOT" count towards your allocated number of pop mail boxes we've provided.
