thank you again for your configuration examples [1].

I have a question regarding exactly how Exim can figure if a list’s
state is open or not. In your example the corresponding part is the
following.

  require_files = SYMPA_HOME/expl/$local_part/config
  condition = ${if 
eqi{${lookup{status}lsearch{SYMPA_HOME/expl/$local_part/config}}}{open}{yes}{no}}
  user = sympa

This does not work for me when I want to use recipient verification [2].
The problem is for recipient verification Exim is not run as user `root`
but as user `exim4` and therefore cannot read the content of
`SYMPA_HOME` which can only be read by the user or the group `sympa`.

        $ ls -l /var/lib/
        […]
        drwxrwx--x 6 sympa      sympa      4096 2009-01-17 18:15 sympa
        […]
        $ sudo ls -l /var/lib/sympa
        total 16
        drwxr-x--- 6 sympa sympa 4096 2009-01-26 13:44 expl
        drwxrwxr-x 3 sympa sympa 4096 2009-01-17 22:31 static_content
        drwxrwx--x 4 sympa sympa 4096 2009-02-01 12:12 wwsarchive
        drwxrwx--x 2 sympa sympa 4096 2008-10-19 21:13 x509-user-certs
        $ sudo ls -l /var/lib/sympa/expl
        drwxr-x--- 6 sympa sympa 4096 2009-01-29 00:00 domain.org
        $ sudo ls -l /var/lib/sympa/expl/domain.org
        drwxr-x--- 4 sympa sympa 4096 2009-01-29 08:43 list
        $ sudo ls -l /var/lib/sympa/expl/domain.org/list/config
        -rw-r----- 1 sympa sympa 942 2009-01-29 08:30 
/var/lib/sympa/expl/domain.org/list/configl

(The `user = sympa` line seems to do something different and seems to be
only important for the transports further on [3].)

So my question is how did you solve that? Did you turn recipient
verification off? Did you add the user `exim4` to the group `sympa`? I
am still holding off of using the brute-force method suggested to me in
[4].


Thanks,

Paul
