I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am attaching logs, can somebody trace the problem

From the logs:
remotename => `', stat=0
>>> .
554 5.1.0 Sender denied

So most likely they are blocking the sender. It could be domain, email address or IP address.

Make sure that you domain/IP is not listed on any of the RBLs.

Also check if the recipient is not blocking your domain or email address.
