Well, why are you trying to "download" this zone in the first place? Are
you trying to be a "stealth" slave for the zone? Without the knowledge or
consent of the zone owner? That sounds a little fishy. If you have a
legitimate reason to be doing regular zone transfers of a zone, then you
should know the zone owner and presumably get them to fix the
RFC violation.

A patch to facilitate standards non-conformance? I have no doubt that
such a thing exists, but I don't think anyone here is likely to help you
find it...

BIND 9 sends EDNS0 probes, and some older implementations don't deal very
well with that. That's one possible explanation among many. If you want
to stop the EDNS0 probes on a server-by-server basis, you can create a
server statement like:

server 1.2.3.4 {
    edns no;
};

You may also want to look at tweaking the "transfer-format" option within
the "server" statement.
