Web Form portlet does not validate "Address From" email field value.
Steps to reproduce:
- Start bundle.
- Deploy web form portlet.
- Add it to a page.
- Go to its configuration.
- Enable Send as email and fill every field except Address From.
The form is saved successfully.
The form should not be saved successfully as the Address From is empty.
Similarly, input some invalid email address, the form can still be saved.
