I try to make the Smartlist to work with qmail. qmail is working fine. Upon sending a mail to a Smartlist list, nothing on the list side is seen, and the /var/log/maillog shows: Aug 11 15:47:39 db3 qmail: 1250023659.091760 new msg 25821488 Aug 11 15:47:39 db3 qmail: 1250023659.091807 info msg 25821488: bytes 1826 from <tom@somedomain$ Aug 11 15:47:39 db3 qmail: 1250023659.093674 starting delivery 50: msg 25821488 to local mylist$ Aug 11 15:47:39 db3 qmail: 1250023659.093993 status: local 1/10 remote 0/20 Aug 11 15:47:39 db3 procmail[18029]: Error while writing to "log" Aug 11 15:47:39 db3 sendmail[18034]: n7BKldCE018034: from=alias, size=0, class=0, nrcpts=0, msg$ Aug 11 15:47:39 db3 qmail: 1250023659.109784 delivery 50: success: flist:_Strange_group_or_user$ Aug 11 15:47:39 db3 qmail: 1250023659.109851 status: local 0/10 remote 0/20 Aug 11 15:47:39 db3 qmail: 1250023659.109873 end msg 25821488 although I had my list permissons as: drwxrwxr-x 11 slist slist 4.0K Jul 31 13:30 slist drwxr-sr-x 8 slist slist 4.0K Aug 5 19:25 slist/mylist -rw-rw-rw- 1 slist slist 0 Aug 5 19:25 slist/mylist/log What could be wrong?
