1) There seems to be something blocking DNS queries to 195.2.85.210.

2) The .ru domain contains a glue record for ns.cases.ru that is different
from the address you're using:

% dig cases.ru. ns @ns.ripn.net

; <<>> DiG 8.1 <<>> cases.ru. ns @ns.ripn.net 
; (1 server found)
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10
;; flags: qr rd; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 2
;; QUERY SECTION:
;;	cases.ru, type = NS, class = IN

;; ANSWER SECTION:
cases.ru.		1D IN NS	ns1.aha.ru.
cases.ru.		1D IN NS	ns.cases.ru.

;; ADDITIONAL SECTION:
ns1.aha.ru.		1D IN A		195.2.80.142
ns.cases.ru.		1D IN A		195.2.64.36

Neither of those nameservers have the MX record you mentioned.  They have
the same serial number as you, though -- did you remember to update your
serial number when you added it?

% dig cases.ru any @ns.cases.ru

; <<>> DiG 8.1 <<>> cases.ru any @ns.cases.ru 
; (1 server found)
;; res options: init recurs defnam dnsrch
