Is there a way to limit respondents to those with a known email address

Is there a way to limit respondents to those with a known email address? Can I limit each email address to one response? This is similar to an election/vote scenario as described in https://help.surveymonkey.com/articles/en_US/kb/Can-I-create-a-poll-or-voting-environment.

Somehow there is a possibility to limit the form submission against certain email address domains by using conditional logic on your form. Here is a sample condition which you can set

Unfortunately, that does not help. We have members using all sorts of domains (e.g. gmail.com, yahoo.com, etc.) and not just those from one domain.

I think you can achieve the limiting of the submission to that one known email address only. Meaning the same email address cannot be used anymore on the 2nd time to submit the form. The email address used will be a unique value of the form.

Example, if I submitted your form using my email jonathan@jotform.com then no other respondent will be able to submit the form using the same email address.
