Hi all, I found when I set main.cf to 740, owner is root and group is postfix.
[11:41:55][use...@nx1:~]# echo "testing" | mail -s "testing" root [11:41:58][use...@nx1:~]# send-mail: fatal: open /etc/postfix/main.cf: Permission denied Does main.cf need world readable? If so, the setting in main.cf will be world readable also. Why does it happen? Since man.cf should be loaded to memory when Postfix start, it should not have file access.
