Changed the mail server. emails stopped coming from ors0 server.

Edit /etc/mail/sendmail.cf for replacing smart relay host from mciexch1 to mciexch2 (Change the ip address) and save the file.

Edit /etc/hosts for replacing host from mciexch1 to mciexch2 (Change the ip address) and save the file.

If we update any of the configuration info while sendmail is running, refresh the sendmail subsystem by issue an SRC refresh command or by sending the daemon a SIGHUP as
#refresh -s sendmail
#kill -1 `head -1 /etc/mail/sendmail.pid`

#head -1 sendmail.pid
#more sendmail.pid
#kill -1 `head -1 sendmail.pid`
#more sendmail.pid
#ps -efgrep mail
#lssrc -s sendmail
#stopsrc -s sendmail
#ps -ef|grep mail
#lssrc -s sendmail
#startsrc -s sendmail -a'-bd -q30m'
#lssrc -s sendmail
#ls
# more sendmail.pid

Test the mail as follow:
log in as oracle
cp .profile temp
sendmail -v oracle
sendmail -v yada@yada.com
cat /dev/null > /var/spool/mail/jayp
cat /dev/null > /var/spool/mail/vogtb
cat /dev/null > /var/spool/mail/doanl
cat /dev/null > /var/spool/mail/root
