<div>... what's the done method of troubleshooting DNS problems that only </div>
<div>affect certain network(s), now that open resolvers are (hopefully) a </div>
<div>thing of the past?</div>
<div><br clear="none">
</div>
<div>I have semi-regularly struggled with troubleshooting email delivery </div>
<div>problems (for example), due to an inability to see what ISP X sees as my </div>
<div>MX record.</div>
<div><br clear="none">
</div>
<div>Onceuponatime I could just query their DNS servers myself. Now it seems </div>
<div>I either have to hope that their helpdesk understand what an MX record </div>
<div>actually is, or try to find a shell account on a machine within their </div>
<div>network to tinker with...</div>

</div>
<div>I didn't realise that DNS was something that was a candidate for a </div>
<div>network of 'looking-glass' systems, but perhaps it is... Need a nice, </div>
<div>rate-limited, hard-to-abuse web-based DNS lookup tool to become commonly </div>
<div>available, perhaps?</div>
