Hello kunalclk,

Seems you have problem with domain name resolution.
Or the domain don't accept mail from your IP.

Are you blacklisted ?
Test with this tools : http://www.mxtoolbox.com/blacklists.aspx

The message you have posted doesn't really explain anything about what is happening. It may well be a straight time out.
If it is a one specific user, then get them to test through OWA, by manually typing the address in. Then use Message Tracking see if there is a delivery attempt.
