The mailer engine may be invoked from the Direct Mail backend module. However, if your newsletters are sent to numerous recipients, this extension provides a mailer engine script that may be configured as a cron task on the server. In this example setting, the mailer engine will be invoked every 5 minutes and will check if any mails need to be sent:

*/5 * * * * /home/....../public_html/typo3conf/ext/direct_mail/res/scripts/dmailerd.phpcron> /dev/null

*/5 * * * * /home/....../public_html/typo3/ext/direct_mail/res/scripts/dmailerd.phpcron> /dev/null

Note that the absolute path to the script must be specified.

Note also that dmailerd.phpcron is a shell script and requires the availability of a PHP binary, "/usr/bin/php”. Depending on your server configuration, you may have to edit the first line of the script to refer to the location of the PHP binary.
