Hmmm, I use policyd-weight to weight several blacklists instead of
blocking complete country IP spaces unconditionally and together with some
local spam filtering with CRM114 at home it keeps spam gets through rate
very comfortable low for more than a year already. I estimate I do not
have more than 20 spam mails marked as unsure in a whole week.The rate is
a bit higher at work, but still quite comfortable, where Zimbra does the
additional spam filtering I think with a learnable Spamassassin setup. But
most mail is blocked by policyd-weight at SMTP level anyway.

So I do not see any need to block complete IP spaces, but your mileage may
vary.

Ciao,
