Can I make customers confirm their email address?

Hi all

Now a days a very common technique is used to verify customers email.

When we send Welcome Email in that email we can send a link with any encryption like MD5. When they click on that link they are redirected to the site where they filled up registration form.

And in database there email status will change to confirmed or with any other related word.

My Admin->Customer Detail is
Customer Approval Status - Authorization Pending - 1

Can I get this facility in Zen Cart 1.3.8a
