qmail-smtpd replacement

["Jay Robertson" <jay@kajayr.com.au>]

I have started using your replacement (magic-smtpd). My reason 
for doing so was to complement a post smtpd filter (crm114) which 
identifies spam after acceptance. I use magic-smtpd to block 
messages which have invalid user addresses and other such 
header anomalies.
I have tried various options for the control files to block (eg) access 
from certain countries such as China and Taiwan using the 
"ip2country" utility and the file country_blacklist containing CN, TW 
etc. I have also done 'echo 1 > use_global_country_blacklist' .
However I am still receiving spam email from these countries, and 
wonder what I am doing wrong in my installation of your magic-
smtpd.
Do you have any suggestions or a reference for me to fix this 
problem.
