I had some mails stuck in outbound queue, it appears my mail server can not resolve target MX hosts, yet, I can resolve it OK from home ISP
how can I t/s this further ? MX points to these two hosts 10 cleanmail01.cdsoft.ie 89.28.178.25 20 cleanmail02.cdsoft.ie 89.28.178.26 I can telnet to smtp port using ip address, all's well --------------- # host cleanmail01.cdsoft.ie ;; connection timed out; trying next origin Segmentation fault (core dumped) # host cleanmail02.cdsoft.ie ;; connection timed out; trying next origin Segmentation fault (core dumped) # host slug.org.au slug.org.au has address 216.239.32.21 slug.org.au has address 216.239.36.21 slug.org.au has address 216.239.34.21 slug.org.au has address 216.239.38.21 slug.org.au mail is handled by 10 slug.linux.org.au. # host slug.linux.org.au slug.linux.org.au has address 192.55.98.182 slug.linux.org.au mail is handled by 10 slug.linux.org.au. dig cleanmail01.cdsoft.ie ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.6 <<>> cleanmail01.cdsoft.ie ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 50935 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;cleanmail01.cdsoft.ie.
