It's supposed to work, yes. And yes - there's a bug in how this is
handled. You need the attached patch first.

When doing this, remember that the macros are simple text-substitutions.
So I'd leave out the "%" in the macros, because you end up with too many
of them they way you have it. Instead, I'd do it like this:

   $DB=(db1|data1|dbase).domain.com
   $MAIL=(mail1|smtp|webmail).domain.com
   $WS=(ws1|fred|wilma).domain.com

   $CRITICAL=($DB|$MAIL)
   $ALL=($DB|$MAIL|$WS)

   HOST=%$CRITICAL
      MAIL tom at domain.com

If in doubt, you can always run "hobbitd_alert --dump-config" to see
what your configuration ends up with - it shows the configuration after
expanding the macros.
