Subject: Postfix incorrect permissions on configurations. Request.
Postfix is setting the following permissions by default on Debian Squeeze. I'm seeing roughly the same on RHEL/CentOS 6.x, this appears to be a requirement of "sendmail.postfix"
0755 /etc/postfix
0644 /etc/postfix/*
0755 /etc/postfix-script
0755 /etc/post-install
Which allows all users to execute these scripts and read configurations. Setting to tighter/more typical permissions (i.e 640) results in: postfix/sendmail[21007]: fatal: open /etc/postfix/main.cf: Permission denied
Thanks
