No. Do an upgrade. If installing from source:
Read the RELEASE_NOTES file for 2.6 and 2.7, then:
% make
% su root
# postfix stop
# make upgrade
# postfix start
If installing from a well constructed package:
Read the RELEASE_NOTES file for 2.6 and 2.7, then:
# postfix stop
# some-command-to-install-updated-package
# postfix start
In either case, save the updated main.cf and master.cf files that
are automatically upgraded as part of the install process.
If the package is not well constructed:
Read the RELEASE_NOTES file for 2.6 and 2.7, then:
# postfix stop
# mkdir -p /etc/postfix/cfsavedir
# cp /etc/postfix/main.cf /etc/postfix/master.cf \
/etc/postfix/cfsavedir/
# some-command-to-install-updated-poorly-constructed-package
# cp /etc/postfix/cfsavedir/main.cf /etc/postfix/cfsavedir/master.cf \
/etc/postfix/
# postfix set-permissions upgrade-configuration
# postfix start
A package is not well contstructed if it fails to preserve and upgrade
your existing main.cf and master.cf files.
