It is possible to manipulate the behaviour of JobScheduler e-mail service.
The JobScheduler e-mail service use a stylesheet config/scheduler_mail.xsl for mail transformation.
It was shipped with the standard installation.
To do that
- create a new stylesheet e.g. config/my_scheduler_mail.xsl as copy of config/scheduler_mail.xsl and edit config/my_scheduler_mail.xsl.
- change the configuration file scheduler.xml as follows:
<spooler>
<config mail_xslt_stylesheet = "config/my_scheduler_mail.xsl">
...
</config>
</spooler>
