It's a bit late here for me to dig to be sure of my answer, but my first guess is that $result is being treated as a string, not a number. If I'm right, and I'm too tired to be sure, then in this case, you can just treat it like a string with
Code:
if [$result -ne "0" ]

Properties of email messages can be specified in a configuration file, and via environment variables. Configuration file Configuration file contains entries in a format "Option = Value". The options are: Subject The subject of the email message. EmailFrom The sender of the email message. EmailTo The recipient of the email message.

Integration with ABRT events reporter-mailx can be used as a reporter, to allow users report problems via email when they decide to do it. This usage is pre-configured in /etc/libreport/events.d/mailx_event.conf: EVENT=report_Mailx reporter-mailx It can also be used to notify administrator automatically when a problem happens. When this is desired, modify the event configuration file to run the tool on the post-create event: EVENT=post-create reporter-mailx OPTIONS

Mailx_EmailTo Recipient of the email message. If nor the environment variable nor the corresponding option is defined, the message is send to "root@localhost".
