One snag in that post MadeInGermany.
Hosts that are a substring of others will cause mismatch with grep (eg DEV and DEV01)

Reason: Removed statement about ping exit code - seems to set error condition if no packets received

check-hostname
check-hostname(1M) System Administration Commands check-hostname(1M)
NAME
check-hostname - check if sendmail can determine the system's fully-qualified host name
SYNOPSIS
/usr/sbin/check-hostname
DESCRIPTION
The check-hostname script is a migration aid for sendmail(1M). This script tries to determine the local host's fully-qualified host name
(FQHN) in a manner similar to sendmail(1M). If check-hostname is able to determine the FQHN of the local host, it reports success. Other-
wise, check-hostname reports how to reconfigure the system so that the FQHN can be properly determined.
FILES
/etc/hosts Host name database
/etc/nsswitch.conf Name service switch configuration file
/etc/resolv.conf Configuration file for name server routines
