Thanks for the quick response Chris, To add clarity, we are running koha 3.02.02.000 on ubuntu linux 10.04.1 We have process message queue on cron as shown below. #KOHA CRONJOBS PERL5LIB=/usr/share/koha/lib/ KOHA_CONF=/etc/koha/koha-conf.xml KOHA_CRON_PATH=/usr/share/koha/bin/cronjobs/ # ADVANCE NOTICES 10   1 * * *  $KOHA_CRON_PATH/advance_notices.pl -c # SEND EMAILS 15   * * * *  $KOHA_CRON_PATH/process_message_queue.pl When i manually run the process message_queue command on the terminal, i get: SMS::Send driver SMS::Send does not exist, or is not installed at /usr/share/koha/lib/C4/SMS.pm line 78 I know SMS::Send is installed and i can actually locate it: # locate SMS::Send /usr/local/share/man/man3/SMS::Send.3pm /usr/local/share/man/man3/SMS::Send::AU::Test.3pm /usr/local/share/man/man3/SMS::Send::Driver.3pm /usr/local/share/man/man3/SMS::Send::Test.3pm So am still stuck.   Benson. --- On Wed, 19/1/11, Chris Cormack <chris@bigballofwax.co.nz> wrote: From: Chris Cormack <chris@bigballofwax.co.nz> Subject: Re: [Koha] Overdue notifications not being sent out To: "benson Mugambi" <mnjoben@yahoo.co.uk> Cc: "koha mailing list" <koha@lists.katipo.co.nz> Date: Wednesday, 19 January, 2011, 9:19 Just for clarity and so someone can help you, are you running 3.0.2 or 3.2.0.   The decimal points are important as you can see. If it is 3.2.0 (3.2.2 is the current stable) do you have process message queue running in cron?

The server is configured to send email using sendmail via a smarthost. I have run a series of tests and established that the system has no issues in forwarding email. However in koha, the system is sending out notifications for new accounts and reservations, but not overdue notifications and reminders. When i check some of the patron's notices, i find too many pending notifications. We have configured messaging appropriately, added the email notifications to cron and it used to work well until we upgraded from koha 3.0. So what could we have done wrong? what can i do to fix this and purge all pending notifications?
