NAME

postfix-nochroot - change /etc/postfix/master.cf to not use chroot

SYNOPSIS

postfix-nochroot

DESCRIPTION

Renames /etc/postfix/master.cf to /etc/postfix/master.cf.bak and creates a new /etc/post‐ fix/master.cf file with every service configured to not use chroot. Every modified line is commented. It also restarts Postfix (to apply the change) and rmoves the unused chroot directories /var/spool/postfix/{etc,lib,usr} . Using a chroot environment makes upgrades more difficult and gets in the way when running SE Linux (without actually providing any security benefit in a SE Linux system).
