Impacted versions

  • installer used: Yes
  • Webserver: Nginx

Hi,
In my logs, I have errors on "Backwards-Compatibility",
Is there any way to rectify that?
I found this in the postfix documentation but I'm afraid to do some bullshit, I'd rather ask first :

Using backwards-compatible default setting chroot=y

The master.cf chroot default value has changed from "y" (yes) to "n" (no). The new default avoids the need for copies of system files under the Postfix queue directory. However, sites with strict security requirements may want to keep the chroot feature enabled after updating Postfix from an older version. The backwards-compatibility safety net is designed allow the administrator to choose if they want to keep the old behavior.

As long as a master.cf chroot field is left at its implicit default value, and the compatibility_level setting is less than 1, Postfix may log the following message while it reads the master.cf file:

postfix/master[27664]: /etc/postfix/master.cf: line 72: using
    backwards-compatible default setting chroot=y

If this service should remain chrooted, then the system administrator should make the backwards-compatible setting "chroot = y" permanent in master.cf. For example, to update the chroot setting for the "smtp inet" service:

# postconf -F smtp/inet/chroot=y
# postfix reload

And here are my logs (logwatch) :

@ghost commented on GitHub (Jan 19, 2018):

I'm running postfix 3.2.4 and none of my services are chrooted, the default for postfix >= 3.0 is chroot = no.

It's safe to follow the postfix documentation and update your master.cd using postconf -F smtp/inet/chroot=n

To fix all the services, backup master.cf and run the following in the same directory as master.cf
grep '^[^ \t#]' master.cf | awk '{ print "postconf -F " $1 "/" $2 "/chroot=n" }' | sh
