SMTP problem

[oldi58]

there seems to be a problem with one of the zonefile entries
in cossacks.x10....
mail can not be deliverd to mail servers that do a reverse lookup for the IP
the answeris following :
------

haraldyxc@freenet.de
SMTP error from remote mail server after RCPT TO:<haraldyxc@freenet.de>:
host mx.freenet.de [195.4.92.9]: 550 inconsistent or no DNS PTR record for 74.86.116.190 (see RFC 1912 2.1)
-----
my mail server (exim) tells me the same

record cossacks.x10hosting. not found

it seems that the ending "com" is missing

Hello
here some additional info.
The prob. seems to be the zonefile entry for cossacks.x10hosting.com
if i do a dig for cossacks.x10hosting.com the result is :
###########
harald@mywkst2:~$ dig @ns1.x10hosting.com cossacks.x10hosting.com

; <<>> DiG 9.4.2 <<>> @ns1.x10hosting.com cossacks.x10hosting.com
; (1 server found)
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 3109
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2

;; QUESTION SECTION:
;cossacks.x10hosting.com. IN A

;; ANSWER SECTION:
cossacks.x10hosting.com. 14400 IN A 74.86.116.190
##########

so the IP-addr is : 74.86.116.190
if i do a reverse lookup for IP 74.86.116.190
i get the following:

###########
harald@mywkst2:~$ dig -x 74.86.116.190

; <<>> DiG 9.4.2 <<>> -x 74.86.116.190
;; global options: printcmd
;; Got answer:

;; QUESTION SECTION:
;190.116.86.74.in-addr.arpa. IN PTR

;; ANSWER SECTION:
190.116.86.74.in-addr.arpa. 86400 IN PTR cossacks.x10hosting.

;; AUTHORITY SECTION:
###########

so the answer PTR entry for a reverse lookup, the name is missing the ending "com"
as you can see.

Maybe this is helpfull.
Best regards
