At the site, on the right, you can see a box for
"DNS lookup" and if you enter and specify
mx in the dropdown menu, it will query the (a,b,c)
servers (their new ones running powerdns), and they authoritatively
state "MX not found."

On the left, there is a box for "dns report" and if you enter you get a full gory report of all the glory of
the zone. So, somehow, the dnsstuff site is 
on the one hand getting authoritative response "no MX" and
the other hand asking my servers for the zone and getting the
full MX, TXT, and other less common records.

Well the dnsstuff query claims that the abc.auth-ns hosts *are*
claiming authority for which is why those hosts
dont return MX, because they don't have any such record, only
a NS record.

Now, their (Sonic's) old server has recursion on, and things
were ducky. Now, their new servers (a/b/c.auth-ns) do not have
recursion on. I wonder if this has any bearing on my problem?
I have an email into sonic support, no answer so far (heh yes
maybe they are hit by the email prob now, but a previous email
to their support got through).

Thanks for this report, I don't know what's going on with that
error though. The smidge host has an IPv6 tunnel and perhaps
there is a transient failure with that? Perhaps force the
ipv4 address of smidge there (

Ahh a message from sonic, perhaps their support can forward
my email from this morning to Kelsey (waves hello).

appreciates all the help from everyone
