Using sendmail without FQDN
Hello Folks,
Am facing an issue regarding sendmail. Sendmail is working on the server but it does not have an FQDN and the server is not connected to internet ie it does not have a public IP, it is in the intranet with 192.xxx.xxx.xx IP. How do we go about sending mail from this sendmail installation?
I have worked previous installations where server had an FQDN, so it was only a matter of configuring the sendmail server to relay mails.
Can anyone help me out with some pointers?

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.

/etc/hosts Host name database
/etc/nsswitch.conf Name service switch configuration file
