Hello,

I'm using dnsmasq as a local caching resolver for several years and upgrade to version 2.91 recently.  It used to work properly in the past, but the queries to dnsmasq can not be replied now.
I have confirmed that my home broadband provider's firewall is blocking query packets with the EDNS0 header, based on a comparison between versions 2.91 and 2.90. 
From the changelog of version 2.91, I also learn that EDNS0 header will be always added when talking to upstream now. 

Therefore, is it possible to add an option to control whether to always add EDNS0 header?

Thanks!
