Ensuring a Specific Domain

There is a method to ensure that form validation applies when an email address must contain a specific domain when submitting a form.  This is described in a Vuture Only article.  Vuture Support should reference the file: "To Ensure Form Validation when Email Address Must Contain a Specific Domain" in the Vuture Only knowledge base. 

Updating the logic/message to cover this use case It will be visible in the code of the HTML

Avoiding a Specific Domain

Another option would be to setup the domain as a form spam rule.  Vuture Support can reference a document called "Form Spam Check Tool" in the Vuture Only knowledge base.  This method this would give an error 500 if someone tried to submit with that domain.

This can be used as a combination so it can both show an error and stop the submission.
