I was testing a new DNSBL, and got the test results shown below: I was under the impression that spamd was supposed to "politely" defer connections from unknown/greylisted hosts. The dialogue below suggests that the assumption is that the unknown host is a spammer (which is true 99% of the time, but still...)
Isn't this a bit "over the top"? Rgds, Jay ----------------- TEST RESULTS ------------------- Date: 20 Feb 2007 03:34:43 -0000 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Your SBL test report Testing your SBL block. See http://www.crynwr.com/spam/ for more info. Please note that this test will not tell you if your server is open for relaying. Instead, it tests to see if your server blocks email from IP addresses listed in various blocking lists; in this case, the SBL list. Here's how the conversation looked from sbl.crynwr.com. Note that some sites don't apply the SBL block to postmaster, so I use your envelope sender as the To: address. I connected to 67.33.XX.YYY and here's the conversation I had: 220 kingcull.cullmail.com ESMTP spamd IP-based SPAM blocker; Mon Feb 19 21:34:43 2007 helo sbl.crynwr.com 250 Hello, spam sender.
