First, check if the process is still there using ps and grep
Second, if you can, try and connect to TCP port 25 and try to get an reaction out of it.

But more fundamentally: if the mail service is down, how do you intent to send a mail telling you it's down? I'd solve that one first.

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 ATTRIBUTES
