Re: getting ordb.org to stop spam with sendmail

Hello Wash

I've read your posting about ordb. How do you implement this service in your 
sendmail? I did find some documentation about this but I'm not sure it's 
correct.

getting ordb.org to stop spam with sendmail

2003-06-17 Thread David Banning 
I am interested in getting my server to bounce mail from open relays.

I have been to the ordb.org site. I have added the suggested line
to my mc files;

FEATURE(`dnsbl', `relays.ordb.org', ` 550 Email rejected due to sending server
misconfiguration - see http://www.ordb.org/faq/\#why_rejected;')dnl

I am using sendmail 8.12.9/8.12.6
I of course recompiled the .mc files, and restarted sendmail.

I have tried to test that it is working by adding;

127.0.0.2  29.66.188.209.relays.ordb.org
 
to my /etc/hosts file, as my ip address is 209.188.66.299

I am still not getting a bounce. I am not seeing anything in /var/maillog

I am looking for a clue as to how to get more info to get this working,
either via a tip from someone, or how I can crank up my logging
to maillog to give me more info. A website that goes into
more depth would be helpful, if anyone knows one.

I believe the ordb dnslists are not free anymore, but that is upto you to
go and find out. Perhaps you already did.
I use the following dnslists:

spamhaus.relays.osirusoft.com : spamsites.relays.osirusoft.com : \
dialups.relays.osirusoft.com : socks.relays.osirusoft.com : \
opm.blitzed.org : sbl.spamhaus.org : proxies.blackholes.easynet.nl


I use Exim, not Sendmail, so I do not know how to test, but suppose
you have a different box, you can temporarily assign the IP to it, then
to

telnet -s  209.188.66.29 ip_of_sendmail_box 25

Then simulate a mail transaction and see what the sendmail says in the log...

I don't think your sendmail.cf got updated, or you would now be running

Yes, it looked that way to me when I checked too.

Dan, your advice seems to contradict the ordb.org website which reads;


How do I test if my mailserver is actually using ORDB.org?

On Unix based systems:

Become the root user:

$ su - Edit /etc/hosts in your favourite editor: # vim /etc/hosts
Add the following line, substituting for your your local systems
inverted IP address: 

127.0.0.2 my reversed IP address.relays.ordb.org

Local system, in this case, refers to the host from which you will
be sending the test email.  You build an inverted IP address by
taking your real IP address (e.g. 62.243.214.83) and inverting the
octets. (e.g. 83.214.243.62).  Once you have accomplished this,
sending email to your protected mail server from your local system
should result in a rejection notice, or whatever you have configured
your system for.

Hm.  I have just never seen sendmail open /etc/hosts on my system. 
After ktracing it I see that it does.

I'm not sure that sendmail predates DNS would be quite the right way to put 
it.  Regardless, sendmail certainly predates the canonical usage of email 
addresses identifying the destination via Internet-based DNS records.  :-)

 yes, it did - I looked in the sendmail.cf file just to confirm that
 the entries were there;
 
 # DNS based IP address spam list relays.ordb.org
 R$* $: ${client_addr}
 R$-.$-.$-.$-$: ? $(dnsbl $4.$3.$2.$1.relays.ordb.org. $: OK $)

 R?$+TMP $: TMPOK
 R?$+  $#error $@ 5.7.1 $:  550 Email rejected due to sending
 server misconfiguration - see http://www.ordb.org/faq/\#why_rejected;

Strange. Recompiling the sendmail.cf should give it the same version number
as your currently installed sendmail binary, 8.12.9 in stead of 8.12.6. Are you
using the stock base system sendmail? Are you absolutely sure the sendmail.cf file
you compiled is also the one sendmail uses?
