You said it won't work "AT ALL." I would like to know why not?
Every policy I want is defined including eliminating the ABUSE with a
global NOMAIL record.
You're right, that one works.
Now suppose that, instead of santronics.com, you were
santronics.homestead.fl.us (domains of this form do exist). The query
for SUBDOMAINS.santronics.homestead._ssp.fl.us wouldn't yield the
desired result.
Steve overstated his case when he said it would not work at all, but it
does not work in general.
