Candidate webform

Hi, I have embedded a candidate form within my website so that candidates can register directly from the site http://marshallwells.zohosites.com/current-vacancies.html the problem is is that once submitted the candidate does not receive an email to confirm the email address and to obtain their password..... is there a rule that can be created where when the candidate registers that they receive an email to confirm that there email address is correct and obtain their password? Thanks
