[tor-relays] Email suggesting to send DNS requests to a specific open DNS

[jpmvtd261@xxxxxxxxxxx]

Hello,

Recently, I installed a new Tor exit node. A few days later, I received an email on the address given in the node contact information. This email suggests to change the DNS server my node use, and gives me a specific IP address to use. 

Here is the mail (obfuscated with sharps) :

EMAIL BEGIN

* Subject : Your TOR node
* Body :
**
** Hello,
**
** I came across your TOR relay on atlas. I run a few relays myself
** along with a bunch of DNS resolvers which are a part of the Open
** Root Server network (ORSN.org) - aimed to fight internet
** censorship and circumvent government surveillance programs
** (ie. prism).
**
** I hope you may be interested in using our anonymous open DNS
** resolvers on your relays.
**
** https://BackplaneDNS.org
**
** Resolver - 172.98.193.4#
**
** Resolver - 162.248.241.9#

EMAIL END

I think it could be an attack. If this person send this email to every new exit node operators, there may be a small percentage of rookie operators who will make the change. I found this webpage about Tor exit nodes and DNS :

What do you think about this email ?
