Using DNS Blacklists (dnsbl) - not working

There are a few posts around here about using dnsbl's so I figured I would add what I needed on the config files and see what happens.

So here is a snip of what I am using (its the /etc/postfix/main.cf):

----
smtpd_recipient_restrictions = permit_sasl_authenticated,
permit_mynetworks,
check_relay_domains,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client bl.spamcop.net,
permit
----

But when I do the sbl test it says its going through perfectly fine.

Am I missing something?

I am using input from this post:
http://www.howtoforge.com/forums/showthread.php?t=7802&highlight=smtpd_recipient_restrictions

 

It must be

Code:

smtpd_recipient_restrictions = permit_sasl_authenticated,
      permit_mynetworks,
      check_relay_domains,
      reject_rbl_client sbl-xbl.spamhaus.org,
      reject_rbl_client bl.spamcop.net,
      permit

(note the whitespace at the beginning of lines 2 - 6)

instead of

Code:

smtpd_recipient_restrictions = permit_sasl_authenticated,
permit_mynetworks,
check_relay_domains,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client bl.spamcop.net,
permit

 

Whitespace is created with what...tab? space?

 

yes, you can use tabs for that...

 

Nope... that didnt work. The only way I can get it to work is by adding the reject_rbl_client to the smtp_sender_restrictions and then it works.

that make sense?

Here is what I tried:

Code:

smtpd_recipient_restrictions = permit_sasl_authenticated,
        permit_mynetworks,
        check_relay_domains,
        reject_rbl_client sbl-xbl.spamhaus.org,
        permit

When I do that, and do the sbl test, it says its not working. But when i have it in the smtp_sender_restrictions it works...like this:

Code:

smtpd_sender_restrictions = reject_rbl_client sbl-xbl.spamhaus.org,
       reject_rbl_client bl.spamcop.net,
       reject_rbl_client relays.ordb.org,
       permit

 

That's strange. Are there any errors in your mail log? Which Postfix version do you use? You can find out by running

Code:

postconf -d | grep mail_version
