Yes, I uncommmented the "user = list" line. I even tried adding "group = list".
Nothing seems to work. I've been working under the assumption that the problem involves file permissions, ownership, or the piping statement in /etc/aliases. flist and the procmail link are owned by root:list. flist is set to execute suid. /usr/bin/procmail is owned by root:mail I have also added /var/list/.bin to PATH for root and in /etc/profile. I've tried having flist and the procmail link owned by list:list. But that did not work. I've experimented with piping statements of "| /bin/bash exec /var/list/.bin/flist <listname>" and "| exec /var/list/.bin/flist <listname>". With the first piping statement I received a message from mail daemon: "exec: exec: No such file or directory ", and with the latter piping statement I received '"exec" command not found for address_pipe transport'. Each time I finish a line of investigation, I remove the SmartList package and reinstall from the .deb file, so that the package is reset to its default configuration and I am not compounding the problem with my experimentations. I would appreciate any further suggestions. Wade Parker
