[Exim] how to reject mail from a domain ???

Hi,

I want to block/reject all mail from some domains... I dug around
the FAQ and found the following and added it to my config file, but
I'm still accepting mail from these spam-engine domains.

what else must I do?

reject_domains:
driver = domainlist
self = fail_hard
domains = *.zzn.com:*.prontomail.com
route_list = * localhost byname

Thanks,
  Brent
