This upgrade of postfix changes some default values in the configuration. As
part of this upgrade, the following will be changed: (1) chrooted components
will be changed from '-' to 'y' in master.cf, and (2) myhostname will be set
to a fully-qualified domain name if it is not already such. The install will
be aborted if you do not allow the change.
