[spamdyke-users] Resolving rDNS with CNAME
Hello! I seems that spamdyke has a problem resolving PTR records of the form: bash$ host zzz.yyy.xxx.www www.xxx.yyy.zzz.in-addr.arpa is an alias for www-xxx-yyy-zzz.reverse.domain.tld www-xxx-yyy-zzz.reverse.domain.tld domain name pointer somehost.otherdomain.tld Logfile output: spamdyke[12086]: DENIED_RDNS_RESOLVE from: [EMAIL PROTECTED] to: [EMAIL PROTECTED] origin_ip: zzz.yyy.xxx.www origin_rdns: somehost. auth: (unknown) The real life example is available but I don't want to post it on the list. I can provide it via email if someone is interessted. Best, Hartmut Wernisch ___ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users

An additional information I forgot on my previous post: the faild reverse lookup uses RFC 2317 - Classless IN-ADDR.ARPA delegation http://rfc.net/rfc2317.html On 23 Oct 07, Hartmut Wernisch wrote: Hello!

Re: [spamdyke-users] Resolving rDNS with CNAME
It looks like spamdyke is functioning correctly. In your log message, it shows origin_rdns: somehost, which means it must have resolved the PTR record. DENIED_RDNS_RESOLVE means that the PTR name (in this case, somehost) does not have an A record. In other words, if you run host somehost, you should see an IP address. NOTE: somehost's IP address does not have to be zzz.yyy.xxx.www (the same as the IP address for the PTR record). It just has to have _any_ IP address. -- Sam Clippinger Hartmut Wernisch wrote: Hello!

thanks for reply! On 23 Oct 07, Sam Clippinger wrote: It looks like spamdyke is functioning correctly. In your log message, it shows origin_rdns: somehost, which means it must have resolved the PTR record. normaly it shows the whole name not only the host portion, but this may only be a string operation issue? DENIED_RDNS_RESOLVE means that the PTR name (in this case, somehost) does not have an A record. In other words, if you run host somehost, you should see an IP address. NOTE: somehost's IP address does not have to be zzz.yyy.xxx.www (the same as the IP address for the PTR record). It just has to have _any_ IP address. somehost.otherdomain.tld has a A record and resolves to the right ip www-xxx-yyy-zzz.reverse.domain.tld does not have an A record but an PTR to somehost.otherdomain.tld which resolves as already mentioned. so I am confused :) -- Sam Clippinger Hartmut Wernisch wrote: Hello!
