Dedicated Server Questions

OK, I’m looking at your information about your dedicated servers, and maybe you can answer some questions.

In your cPanel import information, you mention that the domain cannot be the same name as the cPanel username. As you know, cPanel automatically generates default usernames with a maximum of eight characters based on the domain name.

They remove the dot (such as .us is us). Is that sufficient to allow for proper importing?

When it comes to email, does your dedicated server have its own email system, or must we use the one you provide for all your other customers if we go that route?

Finally, custom or vanity nameservers? Possible?
