If you use virtual domains, you can just copy /etc/shadow to the new machine and tell Cyrus/Courier/[whatever] to use PAM to authenticate with the shadow file. Refer to howtoforge.com for details on virtual domain. If you are going to go ahead with the /etc/{password,shadow,group} route, then you also gotta make sure /home/* has the right UID/GID. -- Alvin Chang Yu-Ming
