[cobalt-users] Changing DNS and Server names on working server

["Karl" <cobalt-users@xxxxxxxxx>]

All, any help would be appreciated...

I have a Raq4i server with about half a dozen domains running on it, each
with their own IP address.  The domain name that is the Machine Server name
is also the DNS Server name (e.g.  DOMAIN-A.COM)

I need to change the name of the server and DNS server names from
DOMAIN-A.COM to DOMAIN-X.COM due to a change in domain ownership.  What is
the best recommended solution for doing this with the least amount of pain
to the users of this machine?  I know they will have to change their DNS
server settings (or will they?  the IP addresses aren't changing) with
Network Solutions, but how will this change effect the delivery of email,
other than the normal DNS change flow through the Net?

Any advice would be appreciated!  Thanks in advance,
