Validate Email Addresses on Forms

[Anonymous]

Is there a way to prevent a user from submitting a form if they have not provided an accurate email address?  Obviously they could make an email up, but I want to be sure that the text is entered with the correct email address format. (name@company.com).

Marketo checks automatically for the @ sign in the email.
You can have some JQuery to check for address containing gmail.com, yahoo.com etc. if you need to only accept company email address.
