Hi -
I am trying to blackist specific emails from submitting a DF form however the blacklist does not behave as it should. Here is how I configured the DF instance:

1. Ticked on the 'Check blacklist for invalid responses' field.
2. Added my custom blacklist faiued message text to the 'Blacklist Failed Message' field.
3. Added the specific email to blacklist as an entry in the 'Blacklist Responses' field.

So far so good. But here's what happens when I test the form using the blackisted email:

1. I enter the blacklisted email and click submit.
2. The form does not submit (which is the correct behavior), however, the form does not display the blacklist failed message. In other words, the form simply re-displays with no message informing the user why it did not submit.
3. I then click the Submit button again and the page throws an Invalid Postback error. See attached fie for the complete error message.
   

I am running DNN Professional v6.6 and DynamicForms v4.10.0.5601.

Can you please review and advise?

Thank you.

I have resolved this issue through the use of a custom RegEx expression instead of the blacklist functionality. So no need to respond to this item.

Thank you.
