More than one Smarts SAM notifer needs to be configured in envirronments where one notifier sends mail to the normal receipents and second to a gateway. In this environment, you would need a second Smarts SAM mail notifier.
To support this configuration, do the following:
BASEDIR/smarts/bin/sm_notify --output[=<file>]
[<param> ...] <notifier>
The --conf parameter is used by the sm_notify command to start multiple Email Notifier Adapters on a single host. If the --conf parameter is not specified, the notifier uses the default configuration file:
<notifier>-notify.conf in BASEDIR/smarts/conf/notifier
