You can also use the is_volatile option. Depending on how your environment is set up, I'd go for creating a new service template in the template.cfg. If everything is the same (check times, notification times, contacts) as another pre-exisintg check, you can configure it with the "use" option and just add the "is_volatile 1" to it. Or create a whole new service definition. The is_volatile essentially triggers a hard state immediate. It does not resend notifications though.

The host in a HARD down state

Any errors in the maillog?

Check the log, am not able to find the errors

Looks like mail is sending without a problem. Have you looked further back into the log for errors that would coincide with nagios object failures (HARD down states)?
