I have a server running Linux RedHat 7.2 and Courier Mail Server 0.35.0-8 and am attempting to install LISTSERV 1.8e. I've gone through the installation instructions as directed in 'u-install.memo' file. I've also followed the instructions for qmail located at: http://www.lsoft.com/manuals/1.8e/unixinst.html#qmail I create the dot-courier files: /home/listserv/.courier Contents: | /usr/lib/courier/bin/preline /usr/local/bin/lsv_amin - s /home/listserv/spool -t listserv /etc/courier/aliasdir/.courier-default Contents: | /usr/lib/courier/bin/preline /usr/local/bin/lsv_amin - s /home/listserv/spool -t $LOCAL After sending mail to a test list (e.g. - TST), I see the following mail log entries: Apr 25 09:58:47 poweredge courierd: completed,id=0000BD85.3EA96831.000002D6 Apr 25 09:58:47 poweredge courierlocal: id=0000BD85.3EA96831.000002D6,from=<[log in to unmask]>,addr=<"|/usr/local/bin /lsv_amin /home/listserv/spool listserv"@domain.com>,status: deferred Apr 25 09:58:47 poweredge courierlocal: id=0000BD85.3EA96831.000002D6,from=<[log in to unmask]>,addr=<"|/usr/local/bin /lsv_amin /home/listserv/spool listserv"@domain.com>: lsv_amin: **Error** Syntax is, lsv_amin spool-directory to-user Apr 25 09:58:47 poweredge courierlocal: id=0000BD85.3EA96831.000002D6,from=<[log in to unmask]>,addr=<"|/usr/local/bin /lsv_amin /home/listserv/spool listserv"@domain.com>: lsv_amin: Unable to deliver mail to: "|/usr/local/bin/lsv_amin Apr 25 09:58:47 poweredge lsv_amin: **Error** Syntax is, lsv_amin spool- directory to-user Apr 25 09:58:47 poweredge lsv_amin: Unable to deliver mail to: "|/usr/local/bin/lsv_amin Apr 25 09:58:47 poweredge courierd: Waiting. shutdown time=none, wakeup time=none, queuedelivering=1, inprogress=1 Apr 25 09:58:47 poweredge courierd: started,id=0000BD85.3EA96831.000002D6,from=<[log in to unmask]>,module=local,h ost=alias!|/usr/local/bin/lsv_amin /home/listserv/spool listserv!2! 2!/etc/courier/aliasdir!!,addr=<alias> Does anyone have any experience with LISTSERV running with Courier Mail or Qmail?
