My conclusion is, that although the check_local_user function is called
and the local user is found (getpwnam() succeeded uid=2001 gid=100) and the
$home variable is set correctly, the access priviliges are not
changed for the following exists command which results in a condition
failure.
I've also tried to replaced the "condition" by a "require_files" statement,
but this doesn't work either. So it seems that there is
no way to use this condition check in combination with an unauthenticated
delivery, except I would alter the directory access
rights.
Routers and transports have the options "user" and "group" (chapters
15 and 24) which allow you to change the user/group that exim runs as
for these actions. For example, the procmail example in chapter 29.6
includes the lines
user = $local_part_data
group = mail
