[Exim] Exim 4.10 is not recognizing local UNIX mail boxes

Hello,
I currently have Exim 4.10 installed on a Sun Ultra Enterprise -2, with
Solaris 8 as my OS.
My configure file passes all tests with no errors. This box is a secondary
MTA for the domain,
and also main mail source for the UNIX users here with local mail boxes in
/var/mail/{user name}.
The problem I encounter is that mail does not get delivered to local mail
boxes, it is deferred, due to the following
error report;

32:49 182VN3-0003gt-00 == {user name}@??? R=unix_users
T=local_delivery defer (-6): mailbox /var/mail/{user name} has wrong uid
(231 != 1069)

Now my mail user I set up for Exim upon building the configuration is exim.
user id for exim is 1069
group is mail and group id is 6.

Need some help on this issue in resolving this group and user id.
