hobbit-alerts multi service for a recipient

Hi I have the following rule into my hobbit-alerts.cfg file:

PAGE=%prod.* COLOR=red SERVICE=!msgs,!rdp

    MAIL=my at email.com  COLOR=red REPEAT=10m RECOVERED DURATION>1m

I would like to know if the SERVICE= tag is correctly declared ... anyone have idea ? I want all Red but not MSGS or RDP sent to the recipient...

Thanks,

Steph.
