Answer 1

You cannot verify if the e-mail ID exists are not. Because, you must establish contact with the yahoo server or any other mail service provider to verify that information.

But you can verify if the input ID is valid; i.e., you can check whether it has the '@' symbol, the domain name(Eg:gmail.com,yahoo.com etc)

Here's the code to validate e-mail in JavaScript. I've included the entire code along with the form to validate e-mail.

Name
e-mail id
Address

I am extremely suspicious of you, my friend. One could think that if you are an employee of a bank you would know what you're doing.



If you're not an employee of a bank, and you're making a banking site, I believe the federal police ought to know about you...
