People,

I've configured Courier to use the dnsbl.sorbs.net blacklist which I know my
computer's dynamically assigned ip is in, but using BLOCK2.

Why? because I'm writing a pythonfilter. The problem is that neither using
os.getenv or os.environ the BLOCK2 env var (which i know should be set, because dnsbl.sorbs.net IS
blocking my IP).

Probably the env var is not available to courierfilters, or pythonfilter is not
forwarding it to my environment, I don't know, but the Courier docs for esmtpd.BLACKLIST state that:

# The BLOCK environment variable is automatically enforced by submit. # Nobody really does anything about BLOCK2, this is mainly for use by # plug-in mail filters. If you want Courier to unilaterally block # mail from IP addresses listed on the RBL and RSS, and you have a separate # filter that keys off BLOCK2, uncomment the following.

And this is my setting:

BLACKLISTS="-block=dnsbl.sorbs.net,BLOCK2"

My IP, as you can tell from my message headers, is: 200.89.180.209

Confirmation that it IS blacklisted: ~ $ host -t a 209.180.89.200.dnsbl.sorbs.net 209.180.89.200.dnsbl.sorbs.net has address 127.0.0.10

Am I wrong to believe that BLOCK2 should be accesible within my pythonfilter?
