Logrotate sets wrong permissions on log files

Issue

• Logs are not created as specified in logrotate file.
• /etc/logrotate.d/zimbra has setting as below:

/var/log/zimbra.log {
    daily
    missingok
    notifempty
    create 0644 zimbra zimbra  <============================= here
    postrotate
      kill -HUP `cat /var/run/syslog*.pid 2> /dev/null` 2> /dev/null || true
    endscript
    compress
}

However, logs created are 0600 root root as below:

-rw-------. 1 root root   233123 Oct  7 08:11 /var/log/zimbra.log
-rw-------. 1 root root    31149 Oct  4 03:10 /var/log/zimbra.log-20201004.gz
