sending particular alert message to particular users

["Camelia Anghel" <canghel (at) cjh.org>]

Hello,
This is how my hobbit-client.cfg and hobbit-alerts.cfg look and I would
like to send the first LOG to some users and the second LOG to different
users.
How do I send an alert based on a warning expression?
 
Hobbit-client.cfg
  HOST=myhost.org
  LOG /var/log/messages %failure*|%failed*|%error*|%Warning* COLOR=red
  LOG /var/log/www_server_4881.log %exceeded* COLOR=red
 
Hobbit-alerts.cfg
HOST=myhost.org
          MAIL user (at) something.org SERVICE=msgs REPEAT=30m COLOR=red
RECOVERED
 
Any help, suggestion will be appreciated
 
Thanks,
