I'm a postfix newbie, and I must say, after using
sendmail for years, it seems far superior!
Now, I have CIDR configured and working as per
the instructions here:
http://www.fadden.com/techmisc/asian-spam.htmI'm also using the /etc/postfix/access hash access table,
where I enter individual IP addresses. But I'm thinking
that instead of maintaining my own list, I could just
use reject_rbl_client, and use a list already maintained
on the Internet. Are there such lists available?
Something like this:
reject_rbl_client blockchina.net
reject_rbl_client blockkorea.net
I've tried using blacklists like relays.ordb.org and
sbl.spamhaus.org before, but found they reject too
much legitimate email.
-Thanks
