My smartlist was running until ... some while ago -- I think it was that I relaxed some folder/file permissions to their "group" for my convenience to look at or modofy files (access to list rc.local.xx etc). Now the list quit working while error shows up in the system maillog:

------ Sep 28 22:40:57 nagrp4 procmail[2762]: Error while writing to "log" Sep 28 22:40:57 nagrp4 qmail: 1254195657.852305 delivery 52: success: flist:_Strange_group_or_user_id/did_0+0+1/ ------

As I do not remember exactly what I changed, suggestions for default file permissions are appreciated!

ps: this rpm install made 'ntp' as the owner/groups; never seen before drwx--s--x 10 ntp ntp 4.0K Aug 30 20:40 list -> drwxr-sr-x 2 root list 4096 Sep 4 14:21 .bin -> -rwxr-xr-x 1 ntp ntp 9659 Aug 30 21:16 arch_retrieve -rwxr-xr-x 1 ntp ntp 456 Jan 18 2007 arch_trunc -rwxr-xr-x 5 root ntp 25432 Jan 18 2007 choplist -rwxr-xr-x 1 ntp ntp 6151 Jan 18 2007 confirm -rwxr-xr-x 1 ntp ntp 3815 Jan 18 2007 confirm_add -rwxr-xr-x 1 ntp ntp 6354 Jan 18 2007 confirm_del -rwxr-xr-x 1 ntp ntp 2491 Jan 18 2007 confirm_sub -rwxr-xr-x 1 ntp ntp 6103 Jan 18 2007 createlist -rwxr-xr-x 1 ntp ntp 1192 Jan 18 2007 cronlist -rwxr-xr-x 1 ntp ntp 818 Jan 18 2007 delink -rwxr-xr-x 1 ntp ntp 3877 Jan 18 2007 digest -rwxr-xr-x 1 ntp ntp 2142 Jan 18 2007 donatelist -rwxr-xr-x 1 ntp ntp 3123 Jan 18 2007 extraddr -rwxr-xr-x 5 root ntp 25432 Jan 18 2007 flist -rwxr-xr-x 1 ntp ntp 3506 Jan 18 2007 flush_digests -rwxr-xr-x 5 root ntp 25432 Jan 18 2007 idhash -rwxr-xr-x 1 ntp ntp 3598 Jan 18 2007 led -rw-r--r-- 1 ntp ntp 1566 Jan 18 2007 mimencap -rw-r--r-- 1 ntp ntp 4363 Jan 18 2007 mimencap.local -rwxr-xr-x 1 ntp ntp 2524 Jan 18 2007 mimesend -rwxr-xr-x 1 ntp ntp 9283 Jan 18 2007 mindlist -rwxr-xr-x 5 root ntp 25432 Jan 18 2007 multigram -rwxr-xr-x 1 ntp ntp 4291 Jan 18 2007 procbounce lrwxrwxrwx 1 root list 17 Aug 30 15:54 procmail -> /usr/bin/procmail -rwxr-xr-x 1 ntp ntp 1944 Jan 18 2007 removelist -rwxr-xr-x 5 root ntp 25432 Jan 18 2007 senddigest -rwxr-xr-x 1 ntp ntp 1223 Jan 18 2007 sendmails -rwxr-xr-x 1 ntp ntp 2112 Jan 18 2007 showlink -rwxr-xr-x 1 ntp ntp 4018 Jan 18 2007 showlist -rwxr-xr-x 1 ntp ntp 3776 Sep 4 14:21 subscribe -rwxr-xr-x 1 ntp ntp 2487 Sep 4 14:21 unsubscribe -rwxr-xr-x 1 ntp ntp 3309 Jan 18 2007 x_command
