Too many timeouts resolving / disabling EDNS messages

[Simon Vallet]

Hi,

having recently upgraded one of our nameservers to 9.5.0b1, we now get
the following into our logs :

too many timeouts resolving 'example.com MX'; disabling EDNS

Digging a little bit shows that BIND now queries every host using EDNS0,
even if dnssec-validation or dnssec-enable is off, which seems overkill.

We get *lots* of messages like this, and even if I know we can prevent
BIND to log these, I'd much rather disable EDNS queries alltogether.
But as I understand it, this is currently not possible -- any particular
reasons for this ?
