Validating Email Address before Storing in Contact while allowing Empty Emails

Hi

We have our Eloqua Environment configured to allow storing Null (Empty) value for Email Address Field in Contacts.

Now, the Issue occurred when we tried to use the email validation option in form, the Validation for an empty email is considered invalid, hence preventing the person from submitting the Form. We need the Validation to make sure that the inserted Emails are valid, but at the same time we need to keep the email as optional.

If we removed the Email Validation in the Form, then the email becomes optional, but the person can insert invalid email (rubbish data) in the email field, and when processing the Form to store the data as contact, the contact is not created since the (Email Address) field in contact doesn't allow an invalid email to be stored.
