Vpopmail Permissions error

[Sumith Ail]

Hello   If I add more than 100 users in a domain the users are created in /home/domains/domain.com/0 folder, but the permissions are set to vpopmail and vchkpw and not to the unix uid which I had set for the domain.   So, these users cannot authenticate from pop3 unless I change there permissions back to the unix user ID.   Any Idea whats going wrong. Do I have to continue by manually change the permissions for the subfolders.   We are using Qmail + Vpopmail 4.9.8-1 (CDB) + Qmailadmin 0.39   Thanks Sumith
