Closes #31513

If an email doesn't match our incoming email patterns on the To header, we fall

exception, when we'd be better off acting as if it was empty.

This reverts merge request !10845

We're going to add another cop that deals with another aspect of
`add_column_with_default`, so we need to separate them.
