Invalid address: (setFrom) contact@https://lo

From: contact@https://www.dunba…..

So this is my problem. My contact form is trying to use this invalid email address as the “from” and it won’t send. I have checked the general settings and everywhere else I can think of but can’t find how this invalid email address is being used by the mailer.

Do you know where I can go to override this address? The Admin address in Settings>General is correct but not used by the form.
