Certification: IPv6 mailserver test resolving to old IP record

[growse]

Hi,

I'm trying to get the IPv6 mailserver test working, but for some reason there's a failure. I put in the email address "ipv6@growse.com", but the response from the AJAX call contains the following:

+:<br />
<b>Warning</b>:  fsockopen() [<a href='function.fsockopen'>function.fsockopen</a>]: unable to connect to [2a01:348:18a::4]:25 (Connection timed out) in <b>/home/ipv6/public_html/certification/modules/system.inc</b> on line <b>428</b><br />
var res = { 0: '0', 1: 'Couldnt get a handle' }; res;

The MX record for growse.com should be mailbot.growse.com, which has an AAAA record of 2001:470:1f09:784::11 (where the mailserver is). A long long while back, that AAAA record was 2a01:348:18a::4, but it's not been there for a long time now. Why would the HE mailserver therefore be trying to connect to 2a01:348:18a::4?

Did you email HE and alert them to this?  It sounds like a DNS entry is stale and just needs flushed.

Same result.  I'd just email ipv6@he.net  (unless broquea sees the problem on here first)

It has just magically started working. I guess DNS was being slow...
