some of emails sent to our domain have been bouncing back. or arriving with 3 to 25 hours delay. I was told that emails from certain domains time out after 60 sec. and my exchange sever is not responding fast enough. is there a way to trace or pin-point where the delay is having place.

If you are getting timeouts after 60 seconds then that isn't a delivery timeout, but a connection time out. The primary cause of that is a firewall scanning SMTP traffic, followed by AV or antispam software on the server itself.
