How to totally disable alerts for a particular host?

I'm not sure I understand the docs here...  is something like this
correct?   

# These rules eliminate printers from warnings/alerts
##HOST=%^pr*.hmgc.mcw.edu
##      IGNORE
HOST=lp4.phys.mcw.edu
        IGNORE
##HOST=%^hp*
##      IGNORE
# Misc hosts we do not want alerts on
##HOST=mac1.hmgc.mcw.edu
##      IGNORE
##HOST=canadeo-disk.brc.mcw.edu
##      IGNORE
##HOST=sharpe.phys.mcw.edu
##      IGNORE
HOST=bc1s7.phys.mcw.edu
        IGNORE
#
# Now on to our regular monitoring rules for things we DO want alerts on
#
HOST=uram.hmgc.mcw.edu
