Khilari,
You can check if sendmail daemon is running,
# ps -ef | grep -i sendmail

Also further you can stop and start sendmail:
# cd /sbin/init.d/
# ./sendmail stop
# ./sendmail start

-then check sendemail process.
-Try with a test mail:
# echo " This is test" | mailx -s "Test sendmail" youremail@domain.com

- Check qith mailq if mails are queued or moving,

Cheers,
Raj.

No hints in the /var/adm/syslog/mail.log file?

If this serer was able to send email out previously and all of a sudden it stopped without you or any other admin messing with sendmail.cf file, then, I'd ask the mail relay server administrators if your server got dropped from the authorized senders' list accidentally.

if you post the screen capture from:

echo test | sendmail -v myemail@mycompany.com

it might help figuring out where the email relay is getting blocked

also another useful command output would be:

grep ^DS /etc/mail/sendmail.cf

Khilary,

Also make suer and to check if the mails are receving by the mail relay server and able to process further,

Log in to the mail relay server:

Relay server can be found by:
#cat /etc/mail/sendmail.cf | gerp ^DS

-and check the mail log file: /etc/mail/log file on the relay server(Usualy for linux mail relay server).

Hth,
Raj.
