# A replacement for Nagios's basic mail system which relies on /bin/mailx and local sendmail config
#
# To use this, just replace the entries in commands.cfg and update your hosts and services from the default "notify-by-email" to use the specific host-notify-by-email or service-notify-by-email
#
# I put this in the plugins directory /usr/local/nagios/libexec but you can put it anywhere. Just update the path
# commands.cfg
#define command{
# command_name host-notify-by-email
# command_line $USER1$/send_mail.pl -n "HOST $NOTIFICATIONTYPE$" -h "$HOSTNAME$" -s "$HOSTSTATE$" -a "$HOSTADDRESS$" -i "$HOSTOUTPUT$" -d "$LONGDATETIME$" -e "$CONTACTEMAIL$"
#}
#
#define command{
# command_name service-notify-by-email
# command_line $USER1$/send_mail.pl -n "SERVICE $NOTIFICATIONTYPE$" -h "$HOSTNAME$" -s "$SERVICESTATE$" -a "$HOSTADDRESS$" -i "$SERVICEDESC$ - $SERVICEOUTPUT$ - $SERVICECHECKCOMMAND$" -d "$LONGDATETIME$" -e "$CONTACTEMAIL$"
