I think it's a design bug because of the permissions on the domains directory in ~vpopmail. I guess vpopmail changes uid/gid before creating the domain directory under that uid so that it doesnt have to later do chown/chgrp. Moreover, if the ~vpopmail/domains directory had world read/write other than user/group read/write, qmail would probablly refuse delivering any mail to that directory path.
