Contact Form 7 Mail Configuration Error

My site URL is https://wcswebs.com and is a staging site.

Mail configuration sporting this error:

Sender email address does not belong to the site domain.

I understand the mail configuration reasons for this error, however, I am simply testing in a non-production environment (url) which is not the actual url it will be.

How do I get around this configuration error so I can test it before making it production? Please be specific.

Thank you!
