bionic (8) postfix-nochroot.8.gz

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/postfix/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).
