Lookups for this domain return a SERVFAIL (by definition temporary)
error, there is no authoritative response that the domain does not
exist:
$ dig -t mx gmail.com.tr
; <<>> DiG 9.8.3-P1 <<>> -t mx gmail.com.tr
;; global options: +cmd

The com.tr domain believes gmail.com.tr exists:
$ dig -t ns gmail.com.tr @ns1.nic.tr.

gmail.com.tr. 43200 IN NS ns4.google.com.
But, google.com does not:
$ dig +norecur -t ns gmail.com.tr @ns1.google.com

I don't know whether this has anything to do with the recent
government mandated DNS redirection in Turkey.
