Hi,

Welcome to LQ
Could you please give us the error messages you receive?
Which distribution are you using?

I am using Red Hat Enterprise Linux 5 and As it is happening during startup service checking and We can go further to login screen.So i couldn't able to see the error message.That moment i have to restart the server and Each time it stop responding after Sendmail service fail.What is the solution???can anyone tell??

In a word server goes hanged after sendmail checking during startup.

Some versions of sendmail take a long time to start up.

What happens if you just wait 10 minutes or so?

It remains hanged after 10 or more minutes so each time i restart the server from that position it gets hanged on the same position....

You could disable sendmail at boot.
Then start sendmail, and see for error messages.

If you are not able to boot you should disable sendmail in single user mode

boot into single user mode (at the grub splash screen, type "a" then " single")

at the prompt in single user mode type "chkconfig --level 5 sendmail off". This will disable starting sendmail at boot.

go into normal mode with "init 5"

once booted:
1) check /var/log/boot.log
2) check /var/log/dmesg
3) check /var/log/lastlog
also check the older versions.

enable sendmail (should be done as root: "chkconfig --level 5 sendmail on")
start sendmail (should be done as root: "service restart sendmail")

check your logfiles again
