Even an e-mail record from the author may not be enough. We have no way of knowing or proving whether an electronic permission is in fact from a person who is authorized to give that licence.
To be honest I suggest that we cross that bridge as and when we come to it -- I'm not sure what more we can reasonably be expected to do when it comes to obtaining confirmation of permission than get a clear statement by email.
