how to define a catch-all in hobbit-alerts.cfg

[Bill Wagner]

I have rules defined for many of my 300+ hosts ( a mix of windows and 
unix servers scattered throughout, and interleaved across,  multiple 
pages.  I want to define a default rule for hosts so that, for example, 
every conn alert goes to my unix administrators.  I have experimented 
with several solutions which do not yield the desired result.  e.g.:

HOST=* EXHOST=<>  # I can't explicitly list all hosts (too many) and 
tried macros consisting of wildcard host names
   MAIL ...

HOST=* EXHOST=<>
    MAIL ... UNMATCHED

if I use only HOST=* then I end up with multiple (sometimes redundant) 
recipients for some hosts and no recipients for hosts not previously 
explicitly defined.

Help?

thanks
