vpopmail issue

[daemonic]

Hiya,

I have a bog standard FC3 install which is all working great in
standard form, but....

....im starting to use system quotas, and as a result i want to
include users mail in with this, so from looking at vadddomain i can
supply the -u flag as below and the resulting mail folders are owned
by the user rather than vpopmail; i.e.
vadddomain -u test test.com
gives;
/home/test/domains/test.com#>ls -al ./
-rw------- 1 test test 34 Feb 9 03:05 .dir-control
drwx------ 3 test test 4096 Feb 9 03:05 postmaster
-rw------- 1 test test 63 Feb 9 03:05 .qmail-default
-rw------- 1 test test 140 Feb 9 03:05 vpasswd
-rw------- 1 test test 2210 Feb 9 03:05 vpasswd.cdb
-rw------- 1 test test 0 Feb 9 03:05 .vpasswd.lock
so now the mail will be included with the system quota, but now
vedlivermail cant seem to deliver to the users folders??

now ive spent the last few hours having a good browse around and a
damn good read, but i cant seem to find the right answer, any pointers
from you guys??

Cheers
