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.

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? -Ruben > ___ > [EMAIL PROTECTED] mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

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 .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. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

getting ordb.org to stop spam with sendmail
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.
