[Exim] Expansion in condition of router - permissions issue

    Quick question... If I have check_local_user in a router, it should run
the router as the local_part user, right?

    If so, then does anything under the condition part also run as the user?
It doesn't seem to as an lsearch lookup in the user's home directory is
failing as follows:

    failed to open /home/{user}/.exim/user.config for linear search:
Permission denied (euid=93 egid=93)

    Apologies if this is a FAQ; but I couldn't find anything specifically
regarding user specific conditions.

    I have checked that exim is installed SUID root, and it is. (It's Dag
Wieers' RPMs w/ exiscan, etc)
