RE: [Declude.JunkMail] REVERSE DNS TEST BROKEN
I don't know what it was but I had named the test REVDNS and it looked like this: REVDNS filter D:\REVDNS.txtx 0 0 This caused a dupe test and didn't work: I then changed it to: DNS filter D:\DNS.txt x 0 0 And the regular REVDNS test didn't run - nothing in the log at normal log level - just wasn't checking REVDNS. Then I changed it to: reverse filter D:\reverse.txt x 0 0 And now Declude is scanning the Reverse DNS. Weird ~ but as long as it is working, I'd just suggest that no one define a test called DNS. not that anyone else would make that silly mistake. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of marc catuogno Sent: Friday, September 17, 2004 8:34 AM To: [EMAIL PROTECTED] Subject: [Declude.JunkMail] REVERSE DNS TEST BROKEN I foolishly was creating a test and called it REVDNS - then realized that it was a duplicate test - I changed the name.

Re: [Declude.JunkMail] REVERSE DNS TEST BROKEN
Mark, That line looks just fine. I would spend some time trying to find if there are any other duplicates lying around in both your Global.cfg and JunkMail files. Also, in your Global.cfg file, make sure that you have the following line: XINHEADERX-Note: This E-mail was sent from %REVDNS% ([%REMOTEIP%]). Or whatever it was that you had in there for this function. I'm guessing that you might have done a search and replace and messed up the variable.

Re: [Declude.JunkMail] Reverse DNS and mail issues
1.) We are failing to receive mail from some places; one being verizon and some within our group are questioning if Declude is somehow preventing the mail from getting through. I do not think that is the case. This should be relatively easy to determine. First, see if you can find the E-mail in the IMail SMTP log files. If there are SMTPD lines for the E-mail, and one of them includes a spool file name, IMail accepted the E-mail. If not, IMail did not accept the E-mail. Then, you can check the Declude JunkMail log file to see what happened to the E-mail. Finally, you can check the IMail SMTP log file for "SMTP-" or "SMTP" log file entries, which would indicate IMail attempting to deliver the E-mail. 2.) I got a note from ARIN that our name server for reverse DNS is a lame name server. I was able to verify this using www.DNSreport.com I have looked into this and undertand that the primary name server for 194.242.199.in-adr.arpa (dns.inet911.com) is not answering authoritatiively. I have checked the configuraton and believe the delegation to be set up correctly. This can get very confusing, and depends on what type of DNS server you are using. However, http://192.168.0.3/tools/lookup.ch?ip=70.194.242.199.in-addr.arpa.&type=PTR&server=dns.inet911.com and http://192.168.0.3/tools/lookup.ch?ip=70.194.242.199.in-addr.arpa.&type=PTR&server=dns2.inet911.com show that your DNS servers are reporting authoritatively for the reverse DNS for 199.242.194.70. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.

Re: [Declude.JunkMail] Reverse DNS and Classless Delegation?
Below is a header of an email processed by Declude today - it sees the RDNS as: >> 202.112.78.63.in-addr.arpa [63.78.112.202] << However, your own http://www.dnsstuff.com/tools/ptr.ch?ip=63.78.112.202 correctly reports: >> smtp.hhbrown.com. << Seems as if Declude doesn't follow the classless delegation and applies different logic than DNSSTUFF? That is correct. The reverse DNS lookup in Declude JunkMail was designed just to check for the presence of a reverse DNS entry (which would count a CNAME as having the reverse DNS, whether or not the CNAME resolved). Now that it is possible to filter on the reverse DNS entries, though, it sounds like we will need to add support for the CNAMEs. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.

RE: [Declude.JunkMail] Reverse DNS
I had a similar problem and had to specify the DNS server used by Junkmail rather than having Junkmail use the one that iMail used.

Scott, This is also marked as failing REVDNS check 194.82.139.3 but it has a PTR record 194.82.139.3 PTR record: mail.stokecoll.ac.uk.

It looks like 207.33.16.83 definitely has a correct reverse DNS entry set up (sometimes one DNS server will return a response, while another says there is no entry). Is this happening for other IPs, or just this one? There's always a chance that the reverse DNS entry was just added, but that's a long shot.

>Country: UNITED STATES > >How I am searching: >Searching for 162.89.86.65.in-addr.arpa PTR at f.root-servers.net: Got >unknown result, sorry! Thanks for pointing this out. We made a change yesterday to the DNS engine, after discovering that it could leak handles (which may have contributed to why it stops responding to all web requests occasionally). With a complete lack of QA, that same fix ended up breaking most of the DNS tools, as they were referencing the old DNS engine. Needless to say, it's fixed now (although there is still the issue of the classless reverse DNS entries). -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.

RE: [Declude.JunkMail] Reverse DNS
Ok, thanks for the help Scott. I guess it is confusing to me. As long as I have a reverse DNS, it is compliant. My first thought was that the reverse DNS had to be for the same domain name. I used the DNS report tool for my virtual domain, and indeed I no longer fail the reverse DNS test. This isn't so difficult after all, why doesn't everyone do it? :) Keep up the good work.

RE: [Declude.JunkMail] Reverse DNS
>Either my situation is different, or I'm not understanding. Your situation is the same -- I was just using the "proper" examples. If you substitute "customer_example.com" for "virtual.example.com" in my example, you'll see what I mean. >My customer, a virtual host on my Imail server, is customerexample.com, with >an MX of mail.customerexample.com and no reverse DNS. It *does* have a reverse DNS. The reverse DNS entry takes an IP address and returns a host name. In this case, both the main domain and the virtual domain will use the same IP address, so they will both have a reverse DNS entry. >I can't solve the reverse DNS issue for mail.customerexample.com. I guess I >have to change the MX to mail.example.com, my server. Is this correct? No. Just so long as mail.customer_example.com's MX record points to a host that has an IP address with a reverse DNS entry there is no problem. For example: customer_example.com. MX 10 mail.customer_example.com mail.customer_example.com A 192.168.100.12 Just so long as 192.168.100.12 has a reverse DNS entry, there will be no problem. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.

Let's say my domain is example.com with an MX of mail.example.com and a reverse DNS of 1.1.1.1.in-addr.arpa mail.example.com. Great, works and is RFC compliant. My customer, a virtual host on my Imail server, is customerexample.com, with an MX of mail.customerexample.com and no reverse DNS. I can't solve the reverse DNS issue for mail.customerexample.com.

All you need is a single reverse DNS entry. Technically, you can have more, but very few programs (if any) can handle more than one reverse DNS entry. There should be no problem sending mail from virtual.example.com even though the reverse DNS entry is mail.example.com. Just so long as a reverse DNS entry exists, there should be no problem. If a remote host doesn't like "virtual.example.com" in this case, it will just check to see if it has an MX/A record. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
