I want to check for validity of a mail id(i mean correctness of a email id and not merely the format)
I can write regex code to check for proper format of mail like
@abc.com is invalid where as xyz@abc.com is a valid format
but how do i make sure that xyz@abc.com is a correct mail id (existent mail id) in java mail api?

Any workarounds and possible solutions highly appreciated.

You can check validity of any mail address by calling a Web service. One web service for this I knew can be found here.

Or Googled the problem.

The Apache Commons Validator library has a class for doing that.
