Hi, In diagnosing why some messages are slipping through, I manually analyzed the headers using spamcop and noticed that spamcop reported a blacklist that wasn't getting scored by declude.
I'm assuming the problem is a DNS timeout when declude is trying to perform the lookup test. I'm changing the DNS servers used by declude but wondering: 1. Is there a way to confirm which DNS server declude is using? I know it either inherits the imail server or used the "DNS..." config line, but is there a status that shows what it actually is using? 2. What is the algorithm? does declude use primary DNS and then secondary DNS also? When a DNS lookup fails, does it retry the same server, switch to the secondary DNS server, or simply move on to the next test? 3. How does DNS caching affect declude? Should we install a "caching-only DNS server and configure it as declude's primary lookup server? Will caching actually cause problems with stale data or help performance? 4. Any general advice on monitoring DNS lookups? Obviously, if DNS is failing it will make declude work poorly. Sorry for all the questions, but the DecludeJunkmail manual doesn't address this and I couldn't find any further info in trying to search the archive of this list --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
