My server's date ( GMT+3)  is OK  ;
Europe/Istanbul  Tue Sep  6 21:00:00 2016 UT = Wed Sep  7 00:00:00 2016 +03 isdst=0 gmtoff=10800

But  when i  look at the mail.log  I see GMT+2 

How can i fix this problem ?

root@mail:/etc# ls -l localtime
-rw-r--r-- 1 root root 2126 Dec 31 14:03 localtime

root@mail:/etc# ls -l /var/spool/postfix/etc/localtime
-rw-r--r-- 1 root root 2126 Dec 31 14:04 /var/spool/postfix/etc/localtime
