I really appreciate your immediate reply. Code snippet what you have provided is returning "valid" for wrong email id. Example ab,cd@test.com

Could you please help me to resolve this issue.

Regards

Here's one discussion thread on the email address subject.
This is NOT a complete solution as one would have to implement the RFC 821, RFC 822, RFC 733.
Use Google to find other sources.
