Temporary storage

The messages temporarily sent to the smtp queue are stored in tiki database table tiki_mail_queue, which has these 3 fields:

  • attempts


Example of cron job in a linux box, for on a Multitiki instance at directory /var/www/tiki, that will send emails from the queue every 5 minutes starting at minute 2 of each hour (see Console and Cron for more details):

2,7,12,17,22,27,32,37,42,47,52,57 * * * * cd /var/www/tiki/;php console.php mail-queue:send > /dev/null 2>&1
