Actually... this is done now at the postfix level, one of the changes
I made to postfix the other night...if I am to understand your
Anyone who sends mail to sarai who claims to be from *.indymedia.org
(including sarai, lists, etc.), who is *not* listed in the mynetworks
parameter will get REJECTED.
How this works is:
First we require a HELO:
smtpd_helo_required = yes
Then in the smtpd_helo_restrictions class we have:
smtpd_helo_restrictions = permit_mynetworks,
This permits mail that is in "mynetworks" (see below to see who is in
it), and then checks the file /etc/postfix/checks/helo_checks to see
if you HELO as any of the following, and if you do, then you are
indymedia.org REJECT You are not in indymedia.org
indymediapr.org REJECT You are not in indymediapr.org
Currently, my networks is set to the following. I dont know what all
of these are, I would like to document or remove the ones we don't know:
mynetworks = 127.0.0.0/8, 184.108.40.206/32, 220.127.116.11/32,
18.104.22.168/24, 22.214.171.124/32 , 126.96.36.199/30, 188.8.131.52/32
The second one is judi, the others are fairly loose netblocks and
should be tightened up or confirmed why they are there.
