> How can I migrate my system to vpopmail without change the username > settings of my users ?
use default domain and learn password options to vpopmail build. then just create accounts using just a shell script with -n option to vadduser. Same time you will have to create .qmail files with email address to username aliases. I asume that you have username like "solt" and email address like "[EMAIL PROTECTED]" right? For every user you will have to create a .qmail file for example .qmail-marcin:soltysiak with a single line: &[EMAIL PROTECTED] in it. Then your users would not even know about transistion :) Solt
