[exim] best way to run geoip

Hi All,

I am running exim 4.x (on a debian system). I am looking at using geoip
to help with my spam scoring..... I was thinking of running it as an
external command (in the rcpt check acl), and if the return does not
include my country code (AU) then mark the headers (i'll see how it goes
at first) does anyone have any examples/advice? (what happens if geoip
freezes, is it possible for exim to recover and continue delivering the
message?)


Thanks in advance,
Andrew.
