Moving users from server --> new server

[Are Haugsdal]

Hi   I am about to move my users from one site to another. The configuration is done in order to have the same path�s etc.   I pach the /home/vpopmail/domains/* to the same place on the new server. When using qmailadmin now, it gives authentification error on the new server.   Any ideas ? The permissions seems to be exactly the same, with the correct user/group.   Are
