Set a chroot directory V8.10 and later
There are times when, for security reasons, you might wish to restrict delivery to a
chroot(8) hierarchy. You might, for example, wish to restrict local spool delivery to a small
subset of the total filesystem. One way to manage such a change is to set up that new directory
hierarchy so that it looks something like this:
/secure/etc/passwd
/secure/etc/group
/secure/etc/mail/sendmail.cf
/secure/etc/mail/aliases.
