Search Again: DNS problems with e-mail From: Alan Ordway Date: Monday, December 20, 2004 Time: 6:09:46 am I seem to be having a problem with some e-mail servers rejecting mail from us because their mail server is saying domain not found. I am able to replicate the problem, but I don't know the cause. For example if I do a 'dig @ns.purdue.edu ihmc.us' I get ; <<>> DiG 9.2.2 <<>> @ns.purdue.edu ihmc.us ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 48922 ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 13, ADDITIONAL: 1 ;; QUESTION SECTION: ;ihmc.us.
