When I installed the e-smith server I gave it a DNS name like ibsgaarden.dyndns.org. Later I obtained a "real" domain name for it (ibsgaarden.dk), and added this a virtual domain with its own i-bay. This has worked nice, but I really would want to use ibsgaarden.dk as the "real" domain name - also because most of my users want mail adresses in this domain. So my question is how to do this most simply, and without having to change users' settings etc.
Any help gratefully appreciated,
Jesper
