Thanks,Petr Novotny !!
I create new qmail users in 'MACHINE_2' before moving the files.
I check all qmail files.
[root@MACHINE_2 ]# ls -al /var/qmail/queue/lock
-rw------- 1 qmails qmail 0 Jan 8 12:32 sendmutex
-rw-r--r-- 1 qmailr qmail 1024 Jan 9 12:32 tcpto
prw--w--w- 1 qmails qmail 0 Jan 9 13:01 trigger
Every file is the right mode and owner that it should be.
Is it possible that qmail remeber the uid number ?
[root@MACHINE_1 ]# id qmaild
uid=519(qmaild) gid=503(nofiles) groups=503(nofiles)
[root@MACHINE_2 ]# id qmaild
uid=506(qmaild) gid=505(nofiles) groups=505(nofiles)
