Hello everyone! I want koha to send emails to patrons for circulation transactions like check out, check in, overdue etc. I have installed postfix. Everything is set I can send emails from commands line. but in patron accounts email status is "pending". When I use following commands. 1. koha-shell library 2. export PERL5LIB="/usr/share/koha/lib" 3. export KOHA_CONF="/etc/koha/sites/library/koha-conf.xml" 4. cd /usr/share/koha/bin/cronjobs above all go fine, but when i use following command: 5. ./process_message_queue.pl this error message appears: connect to localhost failed (Connection refused) connect to localhost failed connect to localhost failed (Connection refused) no (more) retries! at ./process_message_queue.pl line 66. Then in patron accounts, email status changes to "failed". Help Plz.
