I tried with dig, but I still see the difference: dig gives me a Non-
Existent
Domain (NXDOMAIN) status, while Resolv::DNS still wrongly returns my
server as valid MX.

But I have gather some interesting data, thanks to your suggestion of
using tcpdump. Indeed, I can see a difference in activity (see dump
pasted below), but I am not quite sure what to make of it... It looks
like
Resolv::DNS does proceed properly at first, sending an MX query and
getting an NXDOMAIN response. But apparently, it is not satisfied by
that NXDOMAIN reply, and from there, Resolv::DNS continues with 3
other queries: PTR, [|domain], and another PTR.

Have we stumbled upon a bug in Resolv::DNS? I can feel we are getting
a little closer to the answer, but I am still quite puzzled by this
strange
behaviour...

Please find below the tcpdump of both the dig and Resolv::DNS
queries. Any help with interpreting these results and getting to
the root of the issue will be greatly appreciated.
