WordPress 3 Multisite using subdomains.- DNS on Cpanel question

using google to search for answers to how to setup a cpanel”based” domain to use with WordPress 3 Multisite using subdomains (subdomain1.domain.com, subdomain2.domain.com etc.)

answer: “just go to subdomains in Cpanel, use * and point it to public_html”….

that works, but (and here’s the question):

now the good old webmail.domainname.com, cpanel.domainname.com, whm.domainname.com etc. doesn’t work anymore

So, question: how to do it 100% properly, so all normal functionality remains and still enable the subdomain possibility with WP Multisite ?

When you’re adding the wildcard subdomain, you need to make sure it is registered last in your ANAME records. Then make sure all of the static subdomains (webmail.domainname.com, cpanel.domainname.com, etc) appear before it.

When using wildcard subdomains, the server starts at the top of the list and works its way down. If all you have listed is your * subdomain, that will override the server’s defaults (I’m assuming your static subdomains weren’t explicitly set up before). So you need to list the static ones first or you’ll lose them.
