Hi Jeevan
I'd really like to ask you to please try to do your best to analyse your own problems before you post them here. We're all busy, and we don't get paid for supporting this forum. We take time out of our own personal and business lives in order to help others. And while we're happy to help, we'd like to think that you're making at least as much effort as we are to solve your problems.
Once you have tried everything (e.g. Google, the Adobe developer site, samples, tech notes, documentation, experimentation, debugging, testing, trying things, asking your co-workers, your own brain, etc) and still can't solve it, then please at least take the time to provide full information about the problem.
Otherwise, you will tend to either get no answer, or an answer that provides about the same level of information as your question.
For this particular problem, I'd say that you probably have an illegal email address in your string.
