My mistake.</p> <p>I had not noticed it because of the success I have with the greylisting. Spam has decreased dramatically when i started this. Even without the RBL stuff. DSBL is gone but spamhaus is still there but using different servers.</p> <p>I've changed my settings and the documentation to use zen.spamhaus.org. </p> <p>To read more about the different spamhaus server read: <a href="http://www.spamhaus.org/faq/answers.lasso?section=DNSBL%20Usage#202" rel="nofollow">http://www.spamhaus.org/faq/answers.lasso?section=DNSBL%20Usage#202</a> </p> http://diymacserver.com/forum/topic/spam-rbl-errors#post-628 Wed, 14 Jan 2009 23:30:54 +0000 dw 628@http://diymacserver.com/forum/ <p>I've been having some issues the last couple of weeks in receiving e-mail, and having finally noticed some errors in mail.log referencing some RBL spam sites, I looked in to it a bit more.</p> <p>The two RBLs in Richard's /etc/postfix/main.cf are:</p> <pre><code>reject_rbl_client list.dsbl.org, reject_rbl_client sbl-xbl.spamhaus.org,</code></pre> <p>the first, dsbl.org, was giving errors every e-mail, thus deferring them (though not bouncing them, I think). spamhaus.org was often giving errors, but not always. I checked dsbl.org, and it says they've shut the system down:</p> <blockquote><p> DSBL is GONE and highly unlikely to return. Please remove it from your mail server configuration.</p> <p>DSBL was a blocklist specialized in listing open relays and open proxies. To put it simply, DSBL listed IP addresses of computers that could be tricked into sending spam by anybody. This was a very successful strategy. Nowadays open relays and open proxies are rare, spammers hardly ever use them any more and no software seems to come with an open-by-default policy any more.</p> </blockquote> <p> I didn't find much on spamhaus.org (nor did I look too deeply) about the situation. In any case, I've removed both of these from my main.cf file and things are working again.</p> <p>I'd like to hear if anyone knows why I should try to replace these....I guess I'll see if there is a significant increase in spam. </p> http://diymacserver.com/forum/topic/dnsbl-change-zenspamhausorg#post-186 Sat, 11 Nov 2006 19:55:39 +0000 Richard 186@http://diymacserver.com/forum/ Thanks for mentioning, I missed that one... http://diymacserver.com/forum/topic/dnsbl-change-zenspamhausorg#post-185 Sat, 11 Nov 2006 19:43:40 +0000 Michael 185@http://diymacserver.com/forum/ Spamhaus is deprecating sbl+xbl and recommends it's new zen.spamhaus.org DNSBL<br /> <br /> <a href="http://www.spamhaus.org/zen/" rel="nofollow">http://www.spamhaus.org/zen/</a><br /> <blockquote>&gt;If you are currently using sbl-xbl.spamhaus.org you can now replace<br /> &gt;'sbl-xbl' with 'zen' (sbl-xbl.spamhaus.org will eventually become obsolete<br /> &gt;and may in the future be withdrawn from service).<br /> &gt;<br /> &gt;zen.spamhaus.org should now be the only spamhaus.org DNSBL in your<br /> &gt;configuration. You should not use ZEN together with other Spamhaus<br /> &gt;blocklists or you will simply be wasting DNS queries and slowing your mail<br /> queue.</blockquote>
