David, I’ve been trying to find the code for the plugin resolve_sender_host but haven’t had any luck - is that a custom plugin or can you send me the link to it?
Just looking at the below: >>> 100/2 [16025] dns lookup: Trying to resolve A: 127.0.0.1 >>> 100/2 [16025] dns lookup: NS Query: 127.0.0.1 (60240) >>> DNS failure looking for 127.0.0.1 after 0 secs (looked for 1, got 0) 16025 (connect) running plugin: resolve_sender_host 16025 (connect) resolve_sender_host: DEBUG: ip=127.0.0.1 host=localhost domain=localhost 16025 Plugin resolve_sender_host, hook connect returned DECLINED, It appears that resolve_sender_host is trying to do an A query for the IP 127.0.0.1 vs a PTR which is what it should be doing. ― Edward McLain Director of Cloud Architecture Solutions Architect, VCP, CDCDP emcl...@teklinks.com d:205.314.6646 <http://www.teklinks.com/> Please direct all support questions to our support team at host...@teklinks.com <http://mailto:host...@teklinks.com/> or 205.314.6634. -----Original Message----- From: David Favor <da...@davidfavor.com> Date: Friday, July 18, 2014 at 9:07 AM To: Edward McLain <emcl...@teklinks.com> Cc: qpsmtpd <qpsmtpd@perl.org> Subject: Re: qpsmtpd-async weird ParaDNS lookup problem >Ed McLain wrote: >> If using dig you can either do: >> >> dig -x 127.0.0.1 >> >> OR >> >> dig 1.0.0.127.in-addr.arpa PTR >> >> That is going to query the primary name server listed in >>/etc/resolv.conf >> - so unless it has a reverse zone setup for the l27.x block you will not >> get an answer back or you will get an answer like the one you have >>below. > >Same data on for both commands on both servers... > >biz-net2# dig -x 127.0.0.1 | egrep '^[a-z0-9]' >1.0.0.127.in-addr.arpa. 604800 IN PTR localhost. >127.in-addr.arpa. 604800 IN NS localhost. >localhost. 604800 IN A 127.0.0.1 >localhost. 604800 IN AAAA ::1 > >biz-net2# dig 1.0.0.127.in-addr.arpa PTR | egrep '^[a-z0-9]' >1.0.0.127.in-addr.arpa. 604800 IN PTR localhost. >127.in-addr.arpa. 604800 IN NS localhost. >localhost. 604800 IN A 127.0.0.1 >localhost. 604800 IN AAAA ::1 > >> What¹s the actual problem you are trying to solve though?
