*/45 10 * * * /usr/share/koha/bin/cronjobs/message_queue.pl

I don't know what version of Koha you are using. In current Koha, the job is named differently, but can be run with -v for verbose feedback: ./misc/cronjobs/process_message_queue.pl -v Of course, all that does is send out any queued messages. It doesn't create overdue notices. For that, you need to run: misc/cronjobs/overdue_notices.pl Schedule that to occur only ONE TIME per day. -- Joe Atzberger LibLime - Open Source Library Solutions
