Re: [spamdyke-users] DENIED_RDNS_RESOLVE Question
The error DENIED_RDNS_RESOLVE means spamdyke found an rDNS name, but the name it found doesn't forward-resolve to an IP address (any IP address). So even though compxroads.com has an IP, m1.compxroads.com does not, so spamdyke rejected it. -- Sam Clippinger On Mar 24, 2015, at 4:03 PM, Denny Jones via spamdyke-users spamdyke-users@spamdyke.org wrote: Hello, Here's the log entry I'm getting: Mar 24 08:16:09 michael spamdyke[12081]: DENIED_RDNS_RESOLVE from: em...@domina.com to: ema...@domina2.com origin_ip: 173.10.76.81 origin_rdns: m1.compxroads.com auth: (unknown) encryption: TLS reason: (empty) Seems like it shouldn't list a domain if it can't resolve t he RDNS.

Re: [spamdyke-users] DENIED_RDNS_RESOLVE another issue
Actually, DENIED_RDNS_RESOLVE means that spamdyke found a reverse DNS name, but that name doesn't resolve to an IP address. However, because this error can be triggered by temporary DNS problems (slow/unreachable/down servers), spamdyke always issues a temporary rejection code in this situation so the remote server will retry later. This issue seems to be resolved, however. My DNS queries show the name blu0-omc2-s21.blu0.hotmail.com does resolve to an IP address. -- Sam Clippinger David Stiller wrote: I think spamdyke doesn't find the origin_ip listed in the mx's of hotmail.com: # dig mx hotmail.com | grep 65.55.111.96 # host -r 65.55.111.96 96.111.55.65.in-addr.arpa has no PTR record [EMAIL PROTECTED] schrieb: Hi spamdyke is blocking emails like this: Nov 10 09:32:33 mail spamdyke[4015]: DENIED_RDNS_RESOLVE from: [EMAIL PROTECTED] to: [EMAIL PROTECTED] origin_ip: 65.55.111.96 origin_rdns: blu0-omc2-s21.blu0.hotmail.com auth: (unknown) In this case, rdns is ok in both ways. ¿ some help please ? thanks ___ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users ___ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users

Re: [spamdyke-users] DENIED_RDNS_RESOLVE with reverse dns
Using your configuration file, spamdyke is running two rDNS tests on incoming connections. First, it checks if the remote host has an rDNS name at all. If it does not, spamdyke will log DENIED_RDNS_MISSING. Then, it checks if the rDNS name resolves to an IP address. If it does not, spamdyke will log DENIED_RDNS_RESOLVE. To disable that second check (and solve your problem), remove the option reject-unresolvable-rdns from your configuration file.
