<div>There are two separate topics to discuss here.</div>
<div><br></div>
<div>Regarding the &quot;domain not found&quot; error, this could
simply be caused by a slowdown in the gtld.biz servers. In my testing,
there was a long pause while these server names were looked up and
queried - over 26 seconds. While dig is less efficient than named at
working around unresponsive servers (since named is multi-threaded),
there could still be a problem there that would trip up named.</div>
<div><br></div>
<div>You should see if any of the administrators of these other mail
servers will work with you to track down the problem.</div>
<div><br></div>
<div>Regarding the dig query results you're showing, you haven't
replicated the problem, but rather simply misinterpreted the dig
output.</div>
<div><br></div>
<div>In your first query, you're asking ns.purdue.edu to look up your
web server's address (look at the question section if you don't
understand that). However, this server says, as part of its response,
that it's not going to recurse for you - the ra (recursion available)
flag is not present. So what you have discovered is that the server in
question doesn't have your records cached. There are several possible
reasons why this could be, starting with, this server may not do
recursion for anybody.</div>
<div><br></div>
<div>In your second dig command, you've asked 'dig' to recurse for
you, and you've told it to get a list of root servers from the Purdue
name server. We already know that the Purdue name server has a list of
root servers, so 'dig' gets that answer and recurses, eventually
querying your own name server and getting the correct answer. This has
nothing whatsoever to do with the Purdue name server; it merely shows
that the chain of delegation for your domain works as intended, which
brings us back to the question of why the Purdue mail server
(presumably) has trouble finding your mail server.</div>
<div><br></div>
<div>That question, unfortunately, remains unanswered, though you've
succeeded in narrowing down the list of suspects. It's not a problem
on your domain registration.</div>
